I-Polyalkylene glycol yichemisiti yezinto elithile lapho kunezinye iinkomboni ezazihlanganiswa nge-material ngalo. Yiwusetshentliziwe ukuba le nto apho akukho. I-polyurethane yichemisiti yokugcina okunene eyaziwayo kumhlaba wethu.
Ngokuqinisekileyo amandla apho kukhethwa i-polyurethane ngu-polyoxyalkylene polyol. Umthombo omkhulu olwesikhephe leyo ungenziwa ngokubanzi kwiimephu ezidingekayo, njengemfomfo wezityalo okugcweleyo ama-soft foam nokuthi nokuba amapayenti. I-polyurethane yichemical esingabonakali kakhulu - kunjalo amaphrojekthi yakhe akusetyenziswa ngokukhangana, kwiimephu ezihlaba zethu, amacar zethu nokuba imiphumela yethu ifurniture engavumeleli umoya. Ngokushesha, i-soft foam ematshetsha yakho yokulala yayenziwa ukuba sihlale siphakamisane, xa riniba i-rubber kwiitayela zocar zakhiwo sikufuneka singasafeni ngezindlu zethu. I-polyoxyalkylene acrylic polyol yinto eyenza lokhu engavumelekanga, ngoba yinto yonke ulungisa kwindawo yokugcina lwendawo.
I-Polyoxyalkylene polyol inani lokusebenza, iyaphandle kokuba kulisezantsi kwindaweni eliphakamiswayo. UPY isetshenziswa ukukhula ngemva kanye nokuba umthimbu omncane okulula, oyisebenziswayo phakathi komhlaba wethu kunye nezinye izinto zethunywa ezinikezelwe. Ngomvulo wesiyathimba 2021, wahlola ifomu elincane elisetshenziswa kwi-seeti zakarhu yokuvumela ukusuka. Phambi kobuxoki, yinkathelo enkulu yokusetshenziswa kwebhalo ebhalase amaxesha apha apho amaxhasa angasetshenziswa, iindlela yokusetshenziswa kwebhalo ebhalase amaxesha apha apho amaxhasa angasetshenziswa, kunye nombiko yokusetshenziswa kwebhalo ebhalase amaxesha apha apho amaxhasa angasetshenziswa. Ngokushesha lokusebenza kwake, ipolyoxyalkylene polyol ingayazi kuhlanganiswa ukusetshenziswa kwezi zinto ezininzi ezixoxwa kunye neziphumeleyo ngalendaweni.
I-Polyoxyalkylene polyol ineenkomo zakuphiko zokugcina ezikhoyo ukuthi yikho amateka omuhle ukuhlola izinto eziphumaphi. Ngenxa yalokho, kudinga ukukhombisa isizathu esingakwazi ukucabanga ngokulandelayo. Ngokushesha kunjalo nokuhlala ekunene ndawonye okungakusithelwa ngenxa yokuvamiswa. Yayingasebenzi kakhulu, ngoko ke kube lula ukubanjwa ngazo abanye amagcinane ukufika amaxesha edingekayo. I-Polyoxyalkylene polyol isocyanate yingxenye elihlukeleyo lokugcina ngokuba lingakwazi ukubanjwa ngeminyaka eminingi, futhi lingasetyenziswa ukulinganisa into engeziwayo kakhulu. Ukubanjwa ngazo amagcinane angasetyenziswa ukulinganisa imibuyiselwano engaphezulu noma engacabangakho phakathi kwabo.
KwiSANYING, siyaziqondisa ukuba sihlale kakhulu lokusetha umsebenzi wethu wesicelo lesi polyoxyalkylene polyol. Ngokulandelayo, kuninzi izindlela zethu ezifundiswa ukuthi zihlale ngemoya engaphezulu kunye nokubonisa isithuthi, esiyibonisa ukuthi sibuyelele ngaphandle kwezindlu zethu. Isicelo sesikhombisa ukuba sihlale kuhlanganisa uphawu lwenkqubo lepolyoxyalkylene polyol, ukuze lihlale kuzivumelwe kunye nokufinyelelwa kwisezisonto ezimbili, ngaphezu kwalokhu ukuba libizwe njengesithuthi. Siyaziqondisa ukuba sihlale kushintsha indlela yokusebenza yomsebenzi othile ngokukhuphela ukuthola amane ngezindlela ezinhle neziqhatho kuziva ukusetshenziswa kwesi sicelo sesethelo. Ukuthi kungaba sihlale kushintsha amanani amahlukeneyo kunye nokuhlala ngesiphumo.
Uphawu olwazi polyoxyalkylene polyol ulwazi oluninzi kubusemisini besicelo sokuqala. Ngokulandelayo, Sanying naye iyahlala ukuba ibuyeleye indawo yesicelo sokuqala, oyenza ukubuyelela amanye amathetho nokuhlala ukubuyelela amanye amathetho nokuhlala ukubuyelela amanye amathetho. Ukusetshenziswa kuphawu olwazi polyoxyalkylene polyol kunye no-isocyanate ikwahlisele amakhosi ophakathi kwezinhlobo zokubeka ezintathu ezifanekiso kahle ngokwesiphumo sokuthi bayenziwe njengekuqinisekisi, ukusetyenziswa kwamandla kunye nokuhlinzekela. Izilungiselelo zizoba zibheka izindlela zokubulawa, uhlobo lomsebenzi oluningiyo lokusebenza kunye neziqhuthu ezinomsindo.
