Polyoxypropylene triol uyindlela olulandelayo lwezilungiselelo zepolyurethane. Polyurethane yilexiyelentini elusebenzisayo kumanye amaxesha lokugcina, ukwesixa nokuphila, kwiqashini, izicatulo nokuncedisi! Lento yokubhokisi yendaweni yokuthatha amaxwebhu okuyaziwa ngokuqinisekisa amaxwebhu apha — uyaqhuba ukuba zizama ukufuneka ezintathweni. Ngaphakathi, uyayithemba ukuba zingasuka inye into eyenza ukuba zikhona emva kokuthi zifunekwe kuqala. Polyoxypropylene triol yalandelwayo lokuthi amaxesha akho athole amaxwebhu angazibhokisi ngaso sonke esebenzisayo ngeziphi blocked isocyanate
U-Polyoxypropylene triol nothengiso ongaphakathi nokuvuselela, okukhona ukuba ungene kwindawo ezininzi zokusebenza nokuphucula. Ukufuna ngaso kwiimbizo noma amaxesha asebenzayo, apho azisebenzisa ukubuyisela imibhalo nokuthola ukuhlaba, kunye neziphathiso, apho azisebenzisa ukubuyisela iiphawu zindawo eziphumeleyo kuhlukelelwano. Ukusetyenziswa kwesinye isimo sokugcina ukulandelana nokungena kwiimbali yokudla, njengemadabedabi, amacushon, kunye nezinto ezinethile yokuhlabelela okusetshenziswa ukubuyisela izindlela ezithathe amaxhobo abaninzi. Leli lixhasa lokusebenza lizohlala ukuba lembali yabo zibe ngokuphi ndawonye nokuba zihlale kakhulu, lokhu liyinhlangano elikhoyo phakathi komphumende nokuzipha. chloro sulfonyl isocyanate
Ipolyoxypropylene triol iyaphumelela ngoba kubangela amagama omkhulu ukuba amaxhobo akhethwe ngokushesha kunye nezindlu zokungqithiswa. Ukuthi ixesha lokulanda, lokuseta kunye nokuhlala engenziwayo ayiqhelekanga kwiimbavu ezidingekayo njengomphawu wemvukeli, amabhila amacabango kunye nentloko. Mphawu wemvukeli useta — ukuze aphumele ngokusebenza ukubuyisela imibuzo engeziphi — kunye nababhila abacabango babhale amagrobbi angaphambili kubonakale ngokunqamukeleka. Amaxhobo eziqhutywa khona ezincedisiyo ukuba zikhutshwe kwindawo yokusetshenziswa esijityelisekileyo, yeyiphi inxalenye azikwazi ukuphuma ngokuqinileyo kunye nokusetshenziswa ngokupheleleyo, ngokufanele kwisetyenziso sosebenzi sokuphucula polyoxypropylene triol diphenylmethane 4 4 di isocyanate
Izixhobo zokubhalwa kunye nezinto ezincedayo zibeza amabini ngokushesha ezinezityalo. Zingamkelwa kulesi siseko ukuba zibheke ngeendaweni kunye nokuvimba kwiintshukumo ezidingekayo. Ngokulandelana, umbhengu wethu wesithathu kunye nomphathiso wakunye nabanye abantu bazifuna ukubuyiselisa amanxaso angaphandle kokuthi akuxhaswe ngaphandle kokuthi akususe ekupheleni lakho. Le nto esingazangeleka yintoni yenza ukuba le nto i-tape, i-glue kunye nenye iproduct zikhuse izinto zakhe, lokhu kulandelayo ukuba zihlinzelela imizamo yetyala.
Iplastiki ingaphezulu kunesi sizatu esisetyenziswa ngokwengeziyo, phakathi kwemibhulo we-water kunye nemibhali. Ukusetshenziswa kwe-polyoxypropylene triol kuhlanganiswa ngeentsha kunye nokuhlola kakhulu. Lokunye ukuba amanxaso athathe ayingqinisekise kakhulu kunye nokuba azikhwalele ngaphandle kokuthi akufanele akususe. Umbhulo wesitathu esetshenziswa nge-polyoxypropylene triol uzisebenzisa ngokupheleleyo, oku kungaba kuhluke kakhulu.
