Falanqaynta mabda'a iska caabinta biyaha ee nooca budada cinjirka ah ee dib loo cusboonaysiin karo

Budada cinjirka ee dib loo cusboonaysiin karo iyo sibidhka ayaa ah isku xidhka ugu weyn iyo walxaha samaynta filimada ee suufka biyaha u adkaysta. Mabda'a u adkaysta biyaha waa:

Inta lagu jiro habka isku dhafka ah ee budada cinjirka ee dib loo cusboonaysiin karo iyo sibidhka, budada cinjirka ayaa si joogto ah loogu soo celinayaa qaabkii emulsion-ka ee asalka ahaa, qaybaha cinjirka ayaa si isku mid ah ugu kala firdhiya dareeraha sibidhka. Ka dib markii sibidhku la kulmo biyaha, falcelinta fuuq-celinta ayaa bilaabmaysa, xal Ca (OH) 2 waa la buuxinayaa oo crystals ayaa soo degaya, iyo crystals ettringite iyo colloid calcium silicate hydrated isku mar ayaa la sameeyay, qaybaha cinjirka ah ayaa lagu shubaa jel iyo biyo la'aan. qaybaha sibidhka.

Horumarka falcelinta fuuq-celinta, alaabooyinka fuuq-baxa ayaa sii kordhaya, qaybaha cinjirka ayaa si tartiib tartiib ah ugu soo urura meelaha bannaan ee walxaha aan noolaha ahayn sida sibidhka, oo waxay sameeyaan lakab si adag u xiran oo ku yaal dusha sare ee jel sibidhka. Sababtoo ah si tartiib tartiib ah u yaraynta qoyaanka qallalan, qaybaha caatada ah ee dib loo kala firdhiyey ayaa si adag ugu xidhxidhan jelka iyo faaruqinta wadar ahaan si ay u sameeyaan filim joogto ah, samaynta isku dar ah koollada sibidhka oo dhex gala matrix, iyo samaynta koollada sibidhka iyo lafaha kale ee budada ah ee isku dhejiya midba midka kale. . Sababtoo ah qaybaha cirridka ah waxay isku dhejiyaan oo sameeyaan filim ku yaal aagga kala-guurka interfacial ee sibidhka iyo budada kale, aagga kala-guurka ee nidaamka putty waa cufan badan, sidaas awgeed hagaajinta caabbinta biyaha.

Isla mar ahaantaana, kooxaha firfircoon ee ay abuuraan budada cinjirka ah ee dib loo cusboonaysiin karo ka dib dib-u-celinta, sida monomer methacrylic acid functional la soo bandhigay inta lagu guda jiro isku-dhafka emulsion-ka, waxaa ku jira kooxo carboxyl ah, kuwaas oo isku xiri kara Ca2 +, Al3+, iwm. sibidhka alaabada fuuq-celinta calcium culus. , Samee dammaanad buundada gaar ah, hagaajinta qaab-dhismeedka jireed ee hoobiye sibidhka ee engegan, iyo kor u cufan ee interface putty. Qaybaha cinjirka ee dib loo kala firdhiyey waxay sameeyaan filim joogto ah oo cufan oo ku dhex jira meelaha bannaan ee hab-dhiska dhejiska ah.
