Inokumelana okuhle kakhulu nesimo sezulu, ukumelana ne-ozone, ukumelana namakhemikhali, kanye nokumelana nokuguga, kanye nokumelana okuhle kwamafutha, ukubambezeleka komlilo, kanye nezakhiwo zokufaka imibala. Kuhle ...Funda kabanzi -
Wazi kangakanani ngabalawuli be-PVC foaming
1、 Indlela yokwenza i-Foam: Inhloso yokwengeza ama-polymer anesisindo sama-molecule aphezulu kakhulu emikhiqizweni ye-foam ye-PVC ukukhuthaza ukwenziwa kwe-PVC ibe yi-plastic; Okwesibili ukuthuthukisa amandla okuncibilika kwezinto ze-foam ze-PVC, ukuvimbela ukuhlangana kwama-bubbles, nokuthola imikhiqizo ene-foam efanayo; Okwesithathu...Funda kabanzi -
Yiziphi izizathu zokushintsha kombala kwabalawuli be-PVC foaming
Imikhiqizo ye-PVC foaming agent imhlophe, kodwa ngezinye izikhathi iba phuzi uma igcinwe isikhathi eside. Iyini imbangela? Okokuqala, udinga ukunquma ukuthi ngabe kukhona yini inkinga nge-ejenti ekhethiwe ye-foaming agent. I-PVC foaming regulator isebenzisa i-ejenti ye-foaming agent ukubola nokukhiqiza igesi ebangela ama-pores....Funda kabanzi -
Indlela yokuthuthukisa ikhwalithi yabalawuli bezinto ze-PVC foaming
Kunezindlela eziningi zokuthuthukisa ikhwalithi yabalawuli be-PVC foaming. Isici esiyinhloko ukwandisa amandla okuncibilika kwe-PVC. Ngakho-ke, indlela enengqondo ukwengeza izithasiselo ukuthuthukisa amandla okuncibilika nokunciphisa izinga lokushisa lokucubungula. Abalawuli be-PVC foaming bangasiza imikhiqizo ye-PVC foaming ukuhlinzeka...Funda kabanzi -
Ukwazi kangakanani ngezinsiza zokucubungula i-ACR?
I-PVC ibucayi kakhulu ekushiseni. Lapho izinga lokushisa lifinyelela ku-90 ℃, kuqala ukusabela okuncane kokubola kokushisa. Lapho izinga lokushisa lenyuka laya ku-120 ℃, ukusabela kokubola kuyaqina. Ngemva kokushisa ku-150 ℃ imizuzu eyi-10, i-resin ye-PVC ishintsha kancane kancane kusuka kumbala wayo omhlophe wokuqala ...Funda kabanzi -
Isingeniso ekusebenzeni kweziqinisi ze-calcium zinc
Isingeniso ekusebenzeni kwezithambisi ze-calcium zinc: Isithambisi se-zinc senziwa kusetshenziswa inqubo ekhethekile ehlanganisiwe enosawoti we-calcium, usawoti we-zinc, amafutha okugcoba, ama-antioxidants, nezinye izingxenye eziyinhloko. Asikwazi nje ukufaka esikhundleni sezithambisi ezinobuthi njengosawoti webhodwe le-lead kanye ne-organic tin, kodwa ...Funda kabanzi -
Indlela Yokwenza I-PVC Heat Stabilizer
1) Umunca futhi unciphise i-HCL, uvimbele umphumela wayo wokuzivuselela we-auto.
