Codsiga Sodium CMC ee Dahaarka Latex

Sodium carboxymethyl cellulose(CMC) waxay ka heshaa codsiyo badan qaabaynta dahaadhka cinjirka sababtoo ah awooda ay u leedahay inay wax ka beddesho sifooyinka rheological, wanaajiso xasiloonida, iyo kor u qaadida sifooyinka waxqabadka. Dahaarka cinjirka, sida caadiga ah loo isticmaalo warshadaha sida rinjiga, xabagta, dunta, iyo waraaqaha, waxay ka faa'iidaystaan ​​isku darka CMC ujeedooyin kala duwan. Waa kuwan sida sodium CMC loogu dabaqo qaababka dahaarka cinjirka:

1. Beddelka Rheology:

• Xakamaynta Viscosity: CMC waxay u shaqeysaa sidii wax ka beddelka rheology ee dahaarka cinjirka, hagaajinta viscosity si loo gaaro joogteynta codsiga iyo sifooyinka socodka. Waxay ka caawisaa ka hortagga hoos u dhaca ama dareeraha inta lagu jiro codsiga waxayna sahlaysaa dhigaal siman, isku mid ah.
• Wakiilka dhumucda: Sodium CMC waxay u adeegtaa sidii wakiilka dhumucda, kor u qaadaysa jidhka iyo qaabka dahaarka cinjirka. Waxay wanaajisaa dhisidda dahaarka, dhumucda filimka, iyo daboolida, taasoo horseedaysa hagaajinta awoodda qarinta iyo dhammaystirka dusha sare.

2. Xasilinta iyo Joojinta:

• Hakinta Qaybaha: CMC waxa ay caawisaa hakinta qaybaha midabka, buuxinta, iyo waxyaabaha kale ee lagu daro ee ku jira samaynta dahaarka cinjirka Waxay ka hortagtaa dejinta ama kala-saarista maaddooyinka adag, hubinta isku midka ah iyo xasilloonida nidaamka daahan waqti ka dib.
• Kahortagga qulqulka: CMC waxay ka caawisaa ka hortagga qulqulka walxaha ama qulqulka dahaadhka cinjirka ah, ilaalinta kala firdhinta isku midka ah ee qaybaha iyo yaraynta cilladaha sida xargaha, qulqulka, ama daboolka aan sinnayn.

3. Samaynta Filimada iyo Ku-dhejinta:

• Shaqeynta Isku-xidhka: Sodium CMC waxay u shaqeysaa sidii xire, kor u qaadida adhesion ee u dhexeeya qaybaha cinjirka iyo sagxadaha substrate-ka. Waxay sahlaysa samaynta filim isku xidhan inta lagu jiro qalajinta iyo daawaynta, hagaajinta xoogga xajinta, adkeysiga, iyo iska caabinta xoqidda ama diirinta.
• Yaraynta Xiisadda Dusha: CMC waxa ay yaraynaysaa xiisadda dusha sare ee is-dhexgalka-substrate-ka, kor u qaadida qoynta iyo faafinta dahaarka cinjirka dushiisa. Tani waxay kor u qaadaysaa daboolida dusha sare waxayna hagaajinaysaa adhesion ee noocyo kala duwan oo substrates ah.

4. Haysashada Biyaha iyo Deganaanshaha:

• Xakamaynta qoyaanka: CMC waxa ay caawisaa in ay biyaha ku hayso qaabaynta dahaadhka cinjirka, iyada oo ka hortagaysa qalajinta iyo maqaarka wakhtiga kaydinta ama codsiga. Waxay kordhisaa wakhtiga shaqada, taas oo u oggolaanaysa socodka iyo sinnaanta ku filan, waxayna yaraynaysaa halista cilladaha dahaarka sida calaamadaha burushka ama xariijimaha rullaluistuyada.
• Dejinta-dhalaalista: Sodium CMC waxa ay xoojisaa degenaanshaha baraf-dhalashada ee dahaarka cinjirka, yaraynta kala-soocidda wejiga ama xinjirowga qaybaha marka heerkulku is beddelo. Waxay hubisaa waxqabadka joogtada ah iyo tayada ee xaaladaha deegaanka ee kala duwan.

5. Kobcinta Waxqabadka:

• Socodka iyo Heerka Sare ee la hagaajiyay:CMCwaxay gacan ka geysataa hagaajinta socodka iyo sinnaanta sifooyinka dahaarka cinjirka, taasoo keentay in si siman loo dhammeeyo, oogada sare oo lebis ah. Waxay yaraynaysaa cilladaha dusha sare sida diirka liimiga ah, calamadaha burushka, ama jilbalada, kor u qaadaysa soo jiidashada bilicda.
• Crack Resistance: Sodium CMC waxay wanaajisaa dabacsanaanta iyo iska caabinta dildilaaca filimada cinjirka ee engegan, iyadoo yaraynaysa khatarta dildilaaca, hubinta, ama waallida, gaar ahaan kuwa dabacsan ama elastomeric.

6. Hagaajinta pH iyo Dhigid:

• Xakamaynta pH: CMC waxay u adeegtaa sidii pH wax ka beddelka iyo wakiilka kaydinta qaabaynta dahaarka cinjirka, ka caawinta ilaalinta xasilloonida pH iyo waafaqid qaybaha kale ee samaynta. Waxay xaqiijisaa xaaladaha ugu fiican ee xasiloonida cinjirka, polymerization, iyo sameynta filimka.

Gabagabo:

Sodium carboxymethyl cellulose(CMC) waa wax lagu daro isku dhafan oo ku jira qaababka dahaarka cinjirka, oo bixiya faa'iidooyin kala duwan sida wax ka beddelka rheology, xasilinta, dhiirrigelinta adhesion, haynta biyaha, kor u qaadista waxqabadka, iyo xakamaynta pH. Marka lagu daro CMC dahaarka cinjirka ah, soosaarayaashu waxay gaari karaan hagaajinta guryaha dahaarka, waxqabadka codsiga, iyo adkeysiga, taasoo u horseedaysa dhamaystir tayo sare leh, bilicsanaan leh dhamaan noocyada kala duwan ee substrates iyo adeegsiga dhamaadka isticmaalka.
