Zenziwa njani iiprofayili zeselula zePVC?

Iiprofayile ze-PVC zeselula zenziwe ngenkqubo ebizwa ngokuba yi-extrusion.Nantsi isishwankathelo esenziwe lula senkqubo:

1. Imathiriyeli ekrwada: Izinto eziphambili ezisetyenziswa kwiiprofayili zeselula zePVC yintlaka yePVC, iiplasticizers, kunye nezinye izongezo.Ezi mathiriyeli zixutywe kunye ngokwemilinganiselo echanekileyo ukwenza ikhompawundi ye-homogenous.

2. Ukuxuba: I-compound iphinda ifakwe kwi-high-speed mixer apho ixutywe ngokucokisekileyo ukuqinisekisa ukufana kunye nokuhambelana.

3. I-Extrusion: I-compound edibeneyo ifakwe kwi-extruder, engumatshini ofaka ukushisa kunye noxinzelelo kwi-compound, ebangela ukuba ithambe kwaye ibe yi-malleable.Ikhompawundi ethambileyo iye yanyanzeliswa ngedayisi, nto leyo inika ubume obunqwenelekayo kunye nemilinganiselo.

4. Ukupholisa kunye nokubunjwa: Njengoko iphrofayili ekhutshiweyo iphuma kwi-die, ipholisa ngokukhawuleza ngokusebenzisa amanzi okanye umoya ukuqinisa ukuma kwayo kunye nesakhiwo.

5. Ukusika kunye nokugqiba: Emva kokuba iphrofayili ipholile kwaye iqiniswe, inqunyulwa ubude obufunwayo kwaye naziphi na iinkqubo zokugqiba ezongezelelweyo, ezifana nokubhaliweyo komhlaba okanye ukusetyenziswa kombala, kunokufakwa.

Iziphumo zeeprofayili zeselula zePVC zikhaphukhaphu, zomelele, kwaye ziyamelana nokufuma, zizenza zilungele uluhlu olubanzi lwezicelo kulwakhiwo, ifenitshala, kunye namanye amashishini.
