Izinga lokushisa nokukhanya kwelanga kuzothinta isikhathi sokugcinwa kwe-polyester resin engagcwele.Eqinisweni, kungakhathaliseki ukuthi i-polyester resin engagcwele noma amanye ama-resin, izinga lokushisa lokugcina lingcono kakhulu libe ngu-25 degrees Celsius endaweni yamanje.Ngalesi sisekelo, ukwehla kwezinga lokushisa, isikhathi sokufaneleka se-polyester resin engagcwele;lapho izinga lokushisa liphezulu, isikhathi sokuqinisekisa siba sifushane.
I-resin idinga ukuvalwa futhi igcinwe esitsheni sokuqala ukuvimbela ukulahleka kokushintshashintsha kwe-monomer kanye nokwehla kokungcola kwangaphandle.Futhi isembozo somgqomo wokupakisha wokugcina i-resin akufanele senziwe ngethusi noma i-alloy yethusi, okungcono i-polyethylene, i-polyvinyl chloride nezinye izivalo zensimbi.
Ngokuvamile, ezimweni eziphakeme zokushisa, gwema ukukhanya kwelanga ngqo emgqonyeni wokupakisha, kodwa isikhathi sokugcina sisazothinteka, ngoba esimweni sezulu esishisayo, isikhathi se-gel se-resin sizofinyezwa kakhulu, uma kuyi-resin yekhwalithi ephansi. , ngisho Izoqinisa ngokuqondile emgqonyeni wokupakisha.Ngakho-ke, ngesikhathi sokushisa okuphezulu, uma izimo zivuma, kungcono ukuyibeka endaweni yokugcina impahla ene-air conditioning enezinga lokushisa elingaguquki lama-25 degrees Celsius.Uma umkhiqizi engalungiseleli indawo yokugcina impahla ene-air conditioning, kufanele inake ukunciphisa isikhathi sokugcina se-resin.
Kubalulekile ukuqaphela ukuthi i-resin exutshwe ne-styrene kufanele iphathwe njengama-hydrocarbons avuthayo ukuvimbela umlilo.Kufanele kube nokuphathwa okuqinile kwezindawo zokugcina izimpahla kanye nezitshalo ezigcina lolu hlobo lwe-resin, futhi umsebenzi wokuvimbela umlilo kanye nokuvutha kufanele wenziwe ngaso sonke isikhathi.
Izindaba zokuphepha okufanele zinakwe ngesikhathi sokucutshungulwa kwe-polyester resin engagcwele endaweni yokusebenzela
1. I-resin, i-ejenti yokwelapha, kanye ne-accelerator zonke izinto ezivuthayo, ngakho ukuvimbela umlilo kufanele kunakwe, futhi kufanele kugcinwe ngokuhlukana, ngaphandle kwalokho kulula kakhulu ukubangela ukuqhuma.
2. Akumele kube khona ugwayi futhi kungabikho amalangabi avulekile endaweni yokusebenzela yokukhiqiza.
3. Indawo yokusebenzela yokukhiqiza kufanele igcine umoya owanele.Kunezinhlobo ezimbili zokungena komoya waseshabhu, eyodwa ukugcina ukujikeleza komoya wasendlini, ukuze kususwe i-styrene eguquguqukayo nganoma yisiphi isikhathi.Ngenxa yokuthi umhwamuko we-styrene uminyene kunomoya, ukugxiliswa kwe-styrene eduze nomhlabathi nakho kuphakeme kakhulu.Ngakho-ke, i-exhaust vent endaweni yokusebenzela ibekwe kangcono eduze nomhlabathi.Okunye ukusebenzisa amathuluzi nemishini ukuze kuqedelwe indawo yokusebenza.Isibonelo, setha ifeni yokukhipha umoya ehlukile ukuze ukhiphe umhwamuko we-styrene ogxile kakhulu endaweni yokusebenza, noma ukhiphe igesi ephumayo ngepayipi elikhulu lokudonsa elifakwe endaweni yokusebenzela.
4. Ukuze ubhekane nezigameko ezingalindelekile, indawo yokusebenzela yokukhiqiza kufanele okungenani ibe nezindawo zokuphuma ezimbili.
5. I-resin kanye nama-accelerator ahlukahlukene agcinwe ku-workshop yokukhiqiza akufanele abe kakhulu, kungcono ukugcina inani elincane.
6. Ama-resin angazange asetshenziswe kodwa afakwe nama-accelerator kufanele adluliselwe endaweni ephephile futhi agcinwe ngokuhlukana ukuze avimbele ukushisa okukhulu ekuqoqeni futhi kubangele ukuqhuma nomlilo.
7. Uma inhlaka ye-polyester engagcwalisiwe ivuza futhi ibangele umlilo, amagesi anobuthi azokhishwa kule nqubo futhi abeke impilo yomuntu engozini.Ngakho-ke, izinyathelo eziphuthumayo kufanele zithathwe ukubhekana nakho.
