Ngubani K yivali kwiPVC resin?

K Value kwi-PVC Resin: Ngubani ngokwesiphi kunye nangibonakalisekileyo?

Ungathanda ukufunda isihloko sesi 'K value' esetshenziswa ngokuvavanyeka kumhla uma ungukhona osebenzisa ePVC resin. Kodwa, ngubani ngokushesha? K value iyisistema yokuhlola ukudibanisa lokugcina kwi-PVC resin. Iyinkqubo enkulu ethunyelwe ukujudula inombolo ye-Richest Group yesiphumo soku-polymerization xa ungene kwi-PVC kunye nokuba kunyenzekele izinto zakhe.

Amaphethuzi we-K Value

Landelana no-amaphethuzi we-K value kwi-PVC resin ngokuhlu. Yona ingamakelekela imigomo yezinto le-PVC ukuphumelela. Ungabaleka ukuhlola umnoma wemolekulo wesayithi, oku, phakathi, ingamakelekela imigomo yokuhlola, yokusebenza, kunye nezinto zokusetyenziswa kwe-produksi.

Yeyokuqala, lokhu luhluwe amagreyidi a-PVC. Amakhetsi angaphakathi kuyahlukile izinhlobo zokuphola, okugcina nokuthengisa nokusebenza ngenkabi. Ngokuvamile, amakhetsi akudala kahle kulandelana namandla okuningi, kunye nekhetho elikhulu lokuhlola umculo.

Umbaluleko nokusenzeniso kwi-K Value

Umbaluleko ulungelo lodwa lokwesekela olwenziwayo, futhi PVC ayikho ithathu. I-K value lwavela isithombe esilungiselelwa sikhono sokushayelwa ngokubheka pvc-sg-1 abafakamazini bazama ukwenza amandla amahle, amaphupha. Ngokuvamile, ngokusetyenziswa kwe-K value, abafakamazini bazama ukwenza i-PVC enhlangene nezinto ezintsha, ezinikezeli, njengokuba zizoba ukuhlola imvula, ngazo zonke izinto.

Kusenzeniso kukho ingxenye yesekela lesi-PVC elihlukaniswe yinkampani i-K value lwavela ukuthi. Ngokubheka inani lekuphola, pvc-k72-74 umcibane wakwamathisi akuyazi ukubuya ngaphandle kwezinto ezidingekileyo le-PVC, okungavulwa kuhlala kusukela lokuhlola ukuthi singalindelela ukusebenza yayo ngeminyaka emingi elokugcina. Ngisho ukuthi ukuze umcibane wakwamathisi wahlaleke amakhompiyutha angayisebenzisa ngempumelelo ngaphandle komhlaba, isethulo esesikhephe, iintshabalalo, nokuba kakhulu.

Ukuphatha i-Value ye-K

Manje lisebenzisa sikhumbula ukuthi sihlola ukuthi ubani obhalele i-Value ye-K. I-Value ye-K le-PVC luhlinzekiswa nge-viscometer noma i-gel permeation chromatography system, eyenza imphawu noma ikhodi yesimo sokudibanisa kwe-polymer, ngqo. Izifundo zasendaweni zazihlaleke amakhompiyutha apha ame i-Value ye-K yakho, uzokusenzela ukufinyelela uphawu lwabahluwe.

Ukusebenziswa nokuhlola

Ukufundiswa nokuhlola yehlukene ngamabini iimphasho eziphakeme ezazodwa amapheli wakhetha ngalokhu phambi kokuthi bafike le PVC resin. Iibhuthi zezindlela ezifika imibhalo yezililo neentsha yokulula okungavumelekileyo ezizozihlanganisa izicwangciso zakhe. Ukugcina ukubona kwe-K value we-PVC resin esikhethwe kuzoba ukuba ulwandle olunikezayo liphindzele iimeko nokuphumelela.

Kungaba lokuncane ukuba pvc-k57-59 iibhuthi ezamekana K value ngempahla kunye nokuphela ngendawo obungaphezulu ukuthi babekelise abanethengisi. Lento kuhlela ukubonisa ukusuka kwesikhashana, okungumzekelo ofanele kwiindawo ezintathu.

Iinkcukacha ze-K Value kwi-PVC Resin

I-value lesi lisho amaninzi ngaphandle kweSektori ye-PVC, ukuhlala lokhu iparameter elikhulu lephakathi kwezinhlobo. Ukuthi akhawuleze amandla kwe- PVC resins, lokhu libonisa ngokukhulu ngenqanawe yalo. I-PVC enhle ne-K values zikwenza ukwenzela amaphayile, amakhadulo okulungiselelwa, kunye ne-profiles ezidingayo, xa ke K values ezincinci zikwenza ukwenzela izixhobo, imifilimu, kunye neziphetho ezichasene.
