Alaabada fiitamiintu dhammaantood waxaa laga soo qaatay suufka dabiiciga ah ama saxarka alwaax, kuwaas oo lagu soo saaray iyada oo loo marayo. Alaabta unugyada kaladuwan waxay adeegsadaan wakiilo kala duwan oo kaladuwan. Wakiilka etectexytytylyl (HEC) waa Ethyleneneen-ka, wakiilka etecyroxypropylylulose (HPMC) waa noocyo kale oo ah wakiilada kale ee iftiimaya. (chloromethane iyo propylene oxide).
Rinjiga dhabta ah ee szone iyo rinjiga 'latex rinjiga', rinjiga 'latex', hydroxyetyl cellulose waxaa loo isticmaali karaa sidii dhumuc weyn.
Rinjiga dhagaxa dhabta ah waa fududahay in la saadaaliyo sababta oo ah isku darka badan ee isku-darka iyo asir ballaaran. Waa lagama maarmaan in lagu daro dhumuc si loo kordhiyo meyrka si uu u buuxiyo viscosis-ka looga baahan yahay buufinta inta lagu jiro dhismaha, hagaajinta xasilloonida, iyo in la gaaro xoog gaar ah.
Haddii aad rabto inaad ku guuleysato dhagaxa dhabta ah si loo gaaro xoog wanaagsan, iska caabbial biyo ah iyo iska caabbinta cimilada, xulashada qalabka ceeriin iyo qaabeynta caanobooraha ayaa aad muhiim u ah.
Xaaladaha caadiga ah, xaddiga emulsion ee loo isticmaalo rinjiga dhagaxa dhabta ah ee tayo sare leh ayaa aad u sarreeya.
Tusaale ahaan, in ton oo rinjiga dhagaxa dhabta ah, waxaa laga yaabaa inay jiraan 300kg oo ah emullion saafi ah iyo 650kg oo ciid dhagaxa dhagaxa ah oo dabiici ah. Marka ay ku jiraan waxyaabaha adag ee Emulsion-ka ay tahay 50%, mugga 300kg ee emulsion ka dib markii qalajinta ay tahay qiyaastii 150 litir, iyo mugga 650kg ee ciiddu waa 228 litir. Taasi micnaheedu waa, PVC (PVC-gu mugga mugga rinjiga) ee rinjiga dhagaxa dhabta ahi waa 60% waqtigan, sababtoo ah in walxaha ciidda midabka leh ay ku jiraan, rinjiga dhagaxa dhabta ah ee qalalan ayaa laga yaabaa inay kujiraan CPVC (feejignaanta ballaaran ee muhiimka ah). U fiirsashada mugga midabka) qiyaastii. Ilaa iyo inta aad ka walaacsan tahay, haddii aad doorato cellose on viscosity ku habboon, rinjiga dhagaxa dhabta ah waxay sameyn kartaa filim rinji oo dhameystiran oo cufan si ay ula kulmaan saddexda shuruudaha waxqabadka ee dhabta ah ee rinjiga dhagaxa dhabta ah. Haddii nuxurka rinjiga dhagaxa dhabta ahi uu hooseeyo, waxaa lagula talinayaa in la isticmaalo cel-ka-dabool leh viscosity-ka sare ah sida dhumuc (sida 100,000 viscosis ah), gaar ahaan ka dib markii qiimaha cellulose uu wax ka beddelo oo laga dhigo dhagaxa dhabta ah ee waxqabadka rinjiga uu ka fiican yahay.
Qaar ka mid ah soosaarayaasha rinjiga dhaladka dhagaxa ah ee dhakhaatiirta dhabta ah waxay adeegsadaan hydroxypropyl methylrcellellase halkii ay ka heli lahaayeen hydroxyetyl cell-ka qiimaha iyo qodobo kale.
Marka la barbar dhigo labada nooc ee cellulose, bydroxyetyl cellulose wuxuu leeyahay haynta biyaha ka fiican, ma lumin doono haynta biyaha sababtuna tahay gelatin heerkulka sare, wuxuuna leeyahay iska caabin khad ah. Tixgalinta waxqabadka, waxaa lagu talinayaa in la isticmaalo hyroxytyl cell oo leh viscosity oo ah 100,000 oo ah culaysyo rinjiga dhagaxa dhabta ah.
