Budada polymperster polymper (RDP)waa nooc budo ah oo cinjir ah oo lagu celin karo biyo si ay u sameeyaan kala firidhsan xasilloon. Waxaa caadi ahaan loo isticmaalaa dhismaha, gaar ahaan sameynta caqabadaha, guluusyada taayirrada, rinji, rinjiyeyaasha, iyo jaakadaha. Budada waxay bixisaa macaash kala duwan, sida hagaajinta dabacsanaanta, isku dhafka, caabbinta biyaha, iyo cimri-galka.
1. Polymer (qaybta ugu weyn)
Qaybta ugu muhiimsan ee budada polymperser-ka ee polymberser waa polymer, caadiyan latex synthex sida polyvinyl acetate Polyger-ka polymer wuxuu sameeyaa laf dhabarta kala-duwanaanta marka budadu ku daydo.
Polyvinyl acetate (PVA):Badanaa waxaa loo isticmaalaa caqabadaha iyo jaakadaha sababa la xiriira guryahooda adag ee ku dhagan.
Styrene-Buradiene (SRR):Caadiga ah ee ku dhaca codsiyada dhismaha sababtoo ah dabacsanaantiisa iyo cimri dhererkiisa.
Ethylene-vinyl acetate (Eva):Waxaa loo yaqaanaa dabacsanaanteeda iyo guryaha dhajiska ah, oo badanaa loo isticmaalo codsiyada dabacsan.
Doorka:Marka biyaha lagu daro budada, molecules molecules-ka fuuq-baxa ee fuuq-baxa oo ay sameeyaan kala firidhsan xasilloon, iyagoo bixiya guryaha farsamada ee la doonayo sida adhesion, dabacsanaan, iyo iska caabin biyo.
2. Surfacts (Wakiilada ku fida)
Surfacts waa kiimikooyin gacan ka geysaneysa xasilinta budada cinjirka, hubinta inay ku kala firdhiso biyaha ka dib markii lagu celiyo. Waxay yareeyaan xiisadda dusha sare ee udhaxeysa walxaha, fududeynta hannaanka kala firidhsan iyo hagaajinta waxqabadka budada.
Surfactors-ka aan wax laga qaban karin:Kuwaani waxaa badanaa loo isticmaalaa xasilinta kala-guurka iyagoon saameyn ku yeelanaya bixinta ionic.
Surwacts Anionic:Caawinta kahortaga isku-darka walxaha iyo hagaajinta kala firidhsan ee walxaha latex.
CARRUURTA CARRUURTA:Mararka qaarkood waxaa loo isticmaalaa codsiyo gaar ah oo lacagta wanaagsan looga baahan yahay si loo xidho.
Doorka:Surfacdurts waxay gacan ka geystaan hubinta in budaxadu si fudud loogu celin karo kuna kala firidhsan oo xasilloon, iyadoo aan la jabin ama la-darin.
3. Kulo
Kulo-dejiyeyaasha waxaa lagu daraa budada polyperspersler-ka si looga hortago walxaha latex-ka ah ee ka yimaada agglomerating (wadajirka wadajirka). Waxay hubiyaan in markii budadu ku qaso biyo, kala-guurka ka dhalata ay tahay labis labis iyo xasilloon.
Polyethylen glycol (peg):Xasilinta guud ee ka caawiya joojinta kala-guurka kala firidhsan.
Alaabada loo yaqaan 'cluelose':Mararka qaarkood waxaa loo isticmaalaa in lagu wanaajiyo xasilloonida iyo qaboojinta ee kala firidhsan.
Xiddigaha hydrophobiobily ee wax laga beddelay:Kuwaani waxay u dhaqmi karaan sidii xasilinnada qaarkood si looga hortago isku-darka walxaha.
Doorka:Staficileyaashu waxay muhiim u yihiin joogtaynta tayada kala firidhsan ee dheeraadka dheecaanka, hubinta xitaa joogtaynta iyo guryaha arjiga wanaagsan.
4. Qiyaasta
Waxyaabaha buuxsamaya ayaa lagu dari karaa budada cinjirka si ay u yareeyaan qarashka, kor u qaadida guryaha qaarkood, ama wax ka beddelo qaabka wax soo saarka ugu dambeeya. Kuwaas waxaa ka mid ah agabyada sida kaalshiyamka kaalshiyamka ah, TALC, iyo Silica.
Kalsium Carbonate:Caadi ahaan loo isticmaalo buufin ahaan si aad u kordhiso inta badan oo siinta xalka ugu macquulsan ee ku saabsan adheliyadaha iyo jaakadaha.
Talac:Loo adeegsaday hagaajinta socodka socodka iyo xakameynta aragga sheyga.
Silica:Hagaajin kartaa guryaha farsamada gacanta iyo xoqidda caabbinta sheyga ugu dambeeya.
Doorka:Fulders waxaa badanaa lagu daray si wax looga beddelo guryaha rheolololojiyada ee kala-guurka cinjirka, wanaajinta wax-u-dhigga, iyo xakameynta qaabka ugu dambeeya.
5. Waxyaabaha lagu keydiyo
Waxyaabaha lagu keydiyo ee lagu keydiyo sameynta si looga hortago kobaca microbial inta lagu gudajiro kaydinta oo ay joogteeyaan xasilloonida badeecada waqti ka dib. Waxyaabaha lagu keydiyo ee loo yaqaan 'Miserverf' waxaa ka mid ah methylisotiazolinidonne, benzisothiazolininone, iyo wakiillo ka sii daaya.
Methylisotiazolinoone (MIT):Si aad ah u isticmaasho wax ka difaaci kara koritaanka microbial ee budada.
Benzisothiazolinone (xoogaa):La mid ah mit, waxay ka hortagtaa faddaal iyo bakteeriyada bakteeriyada.
Doorka:Ilaaliyeyaasha ilaaliyadu waxay xaqiijineysaa dhererka iyo xasilloonida budada polymperser-ka ee polysis-ka waqtiga lagu keydiyo, ka hortagga sharafdarro ama in ay wasakhoobaan.

Wakiillada is-huruud waa kiimikooyin ka caawisa walxaha cinjirka 'latex' si ay u soo geliyaan wax ku ool ah si wax ku ool ah marka kala fidintu lagu dabaqo substrate. Waxay horumariyaan qaabeynta filimka, taasoo ka dhigeysa in wax soo saarka kama dambeysta ah ay sii dheeraadaan oo u adkaystaan xirashada iyo jeexitaanka.
2,2,4-Trimerethyl-1,3-pentanadiol:Shuble isku mid ah oo loo adeegsado hagaajinta sameynta filimka ee emulsions.
Butty carbitl acetate:Waxaa loo adeegsaday qaar ka mid ah alaabada latex si loogu sameeyo qaab wanaagsan iyo filim filim.
Doorka:Wakiilada is-huruudka ah ayaa horumarinaya waxqabadka FIFTEX FIVERX, hubinta in ay samaysanayso filim siman, filim adag dusha sare.
7.
Qalabka caagga ah waxaa loo isticmaalaa in lagu wanaajiyo dabacsanaanta iyo la-shaqeynta budada polypser-ka dib-u-eegista marka la dabaqo oo dib u soo saar. Waxay yareeyaan heerkulka kala-guurka ee galaaska (TG) ee Polymer, taasoo ka dhigeysa sheyga ugu dambeeya ee dabacsan.
Di-2-Ethylyhehexyl Phthalate (dehp):Calaamadee caan ah oo loo adeegsado waxyaabaha kala duwan ee latex.
Tri-N-Butyl Cintrate (TBC):Badanaa loo isticmaalo aalad aan sunta ahayn ee ku saabsan codsiyada dhismaha.
Doorka:Qalabka caagga ah waxay kor u qaadeen dabacsanaanta dareeraha dheecaanka dheeriga ah ee dheecaanka, wanaajinta awoodda ay u leedahay ka hortagga dildilaaca iyo isqabinta waqti ka dib.
8.Safarrada Ph
Isku-habeeyeyaasha ph ayaa lagu dari doonaa sameynta si loo hubiyo in cinjirka 'latex-ka uu sii wado meel xasilloon, taas oo muhiim u ah xasilloonida kala-guurka iyo waxtarka labadaba maaddooyinka kale.
Ammonium hydroxide: Inta badan loo isticmaalo hagaajinta pH ee qaababka cinjirka.
Sodium hydroxide: Waxaa loo adeegsaday in lagu kordhiyo ph markii loo baahdo.
Doorka:Joogtaynta PH-ga ku habboon waxay xaqiijineysaa xasilloonida dheecaanka cinjirka, maadaama heerarka aadka u daran ee ph ay sababi karaan nabaad-guur ama xasillooni darro qaab dhismeedka.
