Mu zida zambiri zamafakitale, mawilo a rabara angawoneke ngati zowonjezera wamba, koma amakhudza mwachindunji magwiridwe antchito a zida, kukhazikika kwa magwiridwe antchito, ndalama zosamalira, komanso moyo wautumiki. Chifukwa chachikulu chomwe mawilo a rabara a polyurethane akugwiritsidwira ntchito ndi mafakitale ambiri ndichakuti amalinganiza bwino kunyamula katundu, kukana kuwonongeka, kuyamwa kwa shock, ndi kusinthasintha, ndipo amatha kusunga magwiridwe antchito okhazikika m'mikhalidwe yosiyanasiyana yovuta yogwirira ntchito.
Kuchokera pamalingaliro a zinthuzo, polyurethane ndi chinthu cha polima chomwe chimapangidwa ndi momwe polyols ndi isocyanates zimagwirira ntchito. Kapangidwe kake kamkati kali ndi "zigawo zofewa" zomwe zimapangitsa kuti zinthu zikhale zotanuka komanso zolimba, komanso "zigawo zolimba" zomwe zimapangitsa kuti zinthu zikhale zolimba komanso zolimba. Chifukwa cha kuphatikizana kumeneku, mawilo a rabara a polyurethane sakhala osavuta kutha ngati rabara wamba, komanso alibe mphamvu zomangira ngati zipangizo zina zolimba, zomwe zimapangitsa kuti zikhale zosavuta kupeza bwino m'mafakitale.
1. Ubwino waukulu wa magwiridwe antchito a mawilo a mphira wa polyurethane
Kulimba kwa zinthu zosiyanasiyana komanso kusinthasintha kwamphamvu. Mawilo a rabara a polyurethane amatha kusintha kufewa ndi kuuma kwawo malinga ndi njira yogwiritsira ntchito, zomwe zimapangitsa kuti zikhale zoyenera pazochitika zomwe zimafuna kuyamwa kwa kugunda kwa mtima ndi kuchepetsa phokoso, komanso pazochitika zogwirira ntchito zomwe zimafuna kunyamula katundu wambiri komanso kukana kuwonongeka. Kwa makampani, izi zikutanthauza kuti mtundu womwewo wa zipangizo ukhoza kukwaniritsa zosowa zambiri za zida.
Kachiwiri, imakhala yolimba komanso yolimba nthawi yayitali. Polyurethane imawonongeka mofanana ikagubuduzika komanso kukangana kwa nthawi yayitali, ndipo siimakhala ndi mavuto aakulu m'deralo. Izi ndizofunikira kwambiri pazochitika zomwe zimagwiritsidwa ntchito pafupipafupi monga mizere yopangira, zida zonyamulira katundu, ndi magalimoto osungiramo katundu.
Chachitatu, ili ndi mphamvu zabwino zoyamwa ndi kukana kugwedezeka. Zipangizo zikadutsa m'mizere, masitepe, kapena nthaka yosafanana, mawilo a rabara a polyurethane amatha kuyamwa mphamvu ina ya kugwedezeka, kuchepetsa kugwedezeka pa thupi la chipangizocho ndi zida zake zamkati. Pazida zolondola, zida zamagetsi, ndi zida zodziyimira pawokha, izi zimatha kusintha kwambiri kukhazikika kwa magwiridwe antchito.
Chachinayi, kukana kugwedezeka ndi kochepa. Kukankhira mawilo a rabara n'kosavuta, zida zimayenda bwino, zimathandiza kukonza magwiridwe antchito, komanso kungachepetse kugwiritsa ntchito mphamvu pang'ono.
2. Kodi imathetsa mavuto otani pa malo opangira mafakitale?
Mu ntchito zachikhalidwe, mawilo a rabara wamba amatha kusweka mosagwirizana kapena kupanikizika kwa nthawi yayitali, zomwe zingakhudze magwiridwe antchito awo osalala. Ngakhale mawilo achitsulo ali ndi mphamvu zambiri zonyamula katundu, amakhala ndi phokoso, samatenga bwino mphamvu, komanso amatha kuwonongeka pansi. Mawilo a rabara a polyurethane angodzaza mipata iyi.
Pa mzere wopangira womwe umagwira ntchito nthawi zonse, ungachepetse kugwedezeka ndi kupotoka komwe kumachitika chifukwa cha kuwonongeka kosagwirizana kwa pamwamba pa gudumu; Ponena za zida zosungiramo katundu ndi zoyendera, zimatha kulinganiza mphamvu yonyamulira ndi kuyenda kosinthasintha; Pakupanga bwino kapena kupanga zamagetsi, mawilo ena a rabara a polyurethane osinthidwa amathanso kukhala ndi mphamvu zotaya magetsi, zomwe zimathandiza kuchepetsa mphamvu ya magetsi osasunthika pazinthu ndi zida.
Izi zikutanthauza kuti, mawilo a rabara a polyurethane si ongolowa m'malo mwa zipangizo zachikhalidwe, koma athandiza kuti zipangizo zizigwira ntchito bwino nthawi zambiri, zomwe zapangitsa kuti ntchito iziyenda bwino komanso kuti kukonza kukhale kosavuta.
3. Chifukwa chiyani ingayambitse kukweza kapangidwe ka chipangizo
Ubwino wa mawilo a rabara a polyurethane sumangowonekera m'zigawo zake zokha, komanso umakhudza kapangidwe ka makina onse. Chifukwa cha magwiridwe antchito ake abwino pakunyamula katundu, kukana kuwonongeka, komanso kuwongolera kukula, opanga zida adzakhala ndi malo ambiri posankha kukula kwa mawilo, kutalika konse, ndi kapangidwe kake konyamula katundu.
Mwachitsanzo, m'machitidwe ena osungiramo zinthu kapena zida zogwirira ntchito, kugwiritsa ntchito mawilo a rabara a polyurethane kungathandize kukonza kutalika kwa zida ndi kulondola kwa ntchito pamene zikutsimikizira kuti katundu ndi wokwanira; Pakakhala kufunika kogwiritsa ntchito malo ambiri, zida zimatha kuyenda bwino komanso kugwira ntchito bwino kwa katundu kungawongoleredwe kudzera mu kukula kwa mawilo ndi kapangidwe kake koyenera.
Poganizira izi, mawilo a rabara a polyurethane samangothandiza kuti zinthu zigwire bwino ntchito, komanso amalimbikitsa chitukuko cha zipangizo kuti zigwire bwino ntchito, zikhale zolondola kwambiri, komanso kuti zichepetse ndalama zokonzera.
4. Mphamvu yosinthira imapangitsa kuti izi zigwiritsidwe ntchito m'mafakitale ambiri
Ubwino wina woonekeratu wa zinthu zopangidwa ndi polyurethane ndi malo awo akuluakulu osinthira. Makampani amatha kusintha njira yopangira zinthuzo malinga ndi mikhalidwe yosiyanasiyana yogwirira ntchito kuti akwaniritse zosowa zinazake zogwiritsidwa ntchito.
Mwachitsanzo, m'malo otentha kwambiri, kusintha kwa zinthu kungagwiritsidwe ntchito kuti kukhale kokhazikika kwa kutentha; Pazida zomwe zili ndi madontho a mafuta kapena malo opaka mafuta, kukana mafuta kumatha kuwonjezeka; M'malo amagetsi, mankhwala, kapena oyaka moto komanso ophulika omwe amafunikira njira zotsutsana ndi static, ntchito yotsutsana ndi static imatha kuchitika powonjezera zigawo zoyendetsera magetsi.
Kapangidwe kameneka kamapangitsa mawilo a rabara a polyurethane kukhala oyenera osati kokha pa zipangizo zamafakitale, komanso pokonza chakudya, kupanga zamagetsi, kusunga zinthu zokha, zida zolondola, ndi zida zapadera zogwirira ntchito.
5. Njira yopangira zinthu ndi yofunika kwambiri pa ntchito yomaliza
Kagwiridwe ka ntchito ka mawilo a rabara a polyurethane sikuti kokha kumadalira zinthu zokha, komanso kumadalira kwambiri njira yopangira. Njira zosiyanasiyana zingakhudze kufalikira kwa kachulukidwe, umphumphu wa kapangidwe kake, ndi momwe zimagwirizanirana pakati pa pamwamba pa gudumu ndi pakati pa gudumu la thupi la gudumu.
Mwachitsanzo, kuumba kophatikizana kungachepetse mipata ndi kupsinjika, ndikuchepetsa chiopsezo cha kusweka; Njira yoyenera yophikira imathandiza kukonza kukhazikika kwa mawonekedwe ndi mtundu wa pamwamba; Ngati mgwirizano pakati pa pakati pa gudumu ndi wosanjikiza wokutira uli wolimba kwambiri, ungachepetsenso mavuto a kuvulazidwa ndi kuwonongeka panthawi yogwiritsidwa ntchito kwa nthawi yayitali.
Chifukwa chake, pogula, kuwonjezera pa kulabadira dzina la chinthucho, ndikofunikiranso kuganizira ngati njira yopangira ndi yokhwima, ngati kapangidwe ka chinthucho ndi kodalirika, komanso ngati wopanga ali ndi mphamvu zokhazikika zowongolera khalidwe.
6. Poganizira za kugwiritsa ntchito ndi kukonza, mawilo a rabara a polyurethane ali ndi phindu la nthawi yayitali
Ubwino umodzi wa mawilo a rabara a polyurethane pakugwiritsa ntchito ndi wakuti kusintha kwa magwiridwe antchito nthawi zambiri kumakhala kosavuta kudziwikiratu. Kuwonongeka kwake nthawi zambiri kumadutsa mu gawo lokhazikika poyamba, kenako pang'onopang'ono kumafika mu gawo lofunika kwambiri la kuwonongeka. Makampani amatha kukonza kukonza ndikusintha kutengera kutalika kwa ntchito kapena kuchuluka kwa kugwiritsidwa ntchito, m'malo moyembekezera kuti kulephera mwadzidzidzi kuthetsedwe.
Izi ndizofunikira pa kasamalidwe ka chipangizo. Zingachepetse nthawi yogwira ntchito yosakonzekera, kuchepetsa ndalama zokonzera, komanso kuthandiza makampani kukonza zida zosinthira ndi nthawi yokonza moyenera.
Pakapita nthawi, ngakhale kuti mtengo wogulira mawilo a rabara a polyurethane ukhoza kukhala wokwera kuposa wa zipangizo wamba m'mamodeli ena, mtengo wonse wogwiritsira ntchito nthawi zambiri umakhala wopindulitsa kwambiri poganizira zinthu monga nthawi yogwira ntchito, kuchuluka kwa kukonza, kutayika kwa nthawi yogwira ntchito, komanso mphamvu yoteteza zida.
Chidule
Chifukwa chomwe mawilo a rabara a polyurethane angathandizire kukweza ntchito zamafakitale si chifukwa chakuti chizindikiro chimodzi ndi chabwino kwambiri, koma chifukwa chimapangitsa kuti pakhale mgwirizano wabwino pakati pa kunyamula katundu, kutopa, kugwedezeka, chete, kusinthasintha, komanso kusinthasintha.
Kwa makampani, kusankha mawilo oyenera a rabara la polyurethane sikuti kungosintha gudumu limodzi lokha, komanso kukonza kukhazikika kwa zida, kugwira ntchito bwino, komanso kufunika kwa nthawi yayitali. Ngati momwe zinthu zilili bwino komanso kusankha kuli koyenera, mawilo a rabara la polyurethane akhoza kukhala gawo lofunikira pakukonza njira zamafakitale ndikuchepetsa ndalama zonse.
