Daawooyinka Cayayaanka waa maaddooyin caawiye ah oo lagu daray inta lagu guda jiro habaynta ama codsiga qaabaynta sunta cayayaanka si loo hagaajiyo sifooyinkooda physicochemical, oo sidoo kale loo yaqaan addjuncts sunta cayayaanka. Iyadoo adjuvants laftoodu guud ahaan ay leeyihiin wax yar ama aan lahayn dhaqdhaqaaq bayooloji, waxay si weyn u saameyn karaan waxtarka xakamaynta cayayaanka. Isticmaalka baahsan iyo horumarinta cayayaanka cayayaanka, kala duwanaanshahooda ayaa sii waday ballaarinta, samaynta xulashada saxda ah ee saxda ah caqabada labaad ee ugu weyn ee beeralayda ka dib markii ay doortaan sunta cayayaanka lafteeda.
1.Adjuvants Ka Caawiya Kala firdhinta Walxaha Firfircoon?
Soo-buuxiyeyaasha iyo Qaadayaasha?
Kuwani waa macdano adag oo aan firfircoonayn, warshad ku salaysan, ama qalab synthetic ah oo lagu daray inta lagu guda jiro habaynta hababka sunta cayayaanka adag si loo hagaajiyo diiradda badeecada ugu dambeysa ama loo hagaajiyo xaaladdeeda jireed. Buuxiyeyaasha waxaa loo isticmaalaa in lagu milo maaddooyinka firfircoon oo kor loogu qaado kala firdhisanaanteeda, halka sidayaal sidoo kale u adeegaan si ay u xajiyaan ama u qaadaan qaybaha waxtarka leh. Tusaalooyinka caadiga ah waxaa ka mid ah dhoobada, dhulka diatomaceous, kaolin, iyo dhoobada dhoobada.
Buuxiyeyaasha sida caadiga ah waa walxo aan dabiici ahayn oo dhexdhexaad ah sida dhoobada, dhoobada dhoobada, kaolin, dhulka diatomaceous, pyrophyllite, iyo budada talcum. Shaqadooda aasaasiga ah waa inay milmaan walxaha firfircoon oo ay ku dhejiyaan. Inta badan waxaa loo isticmaalaa soo saarista budo, budo la qoyan karo, granules, iyo granules biyaha la firdhiyo. Isku darka sunta cayayaanka iyo bacriminta ee hadda caanka ah (ama “Bacriminta la daaweeyey”) u isticmaal bacriminta sida sideyaasha sunta cayayaanka, isku darka labada si loo gaaro codsi midaysan.
?Sidayaal Kaliya ma baabi'in walxaha firfircoon, laakiin sidoo kale waxay kaa caawinayaan in la nuugo, iyada oo door muhiim ah ka ciyaaraysa xasilloonida qaabeynta.
·Xalka?
Walxaha dabiiciga ah ee loo isticmaalo in lagu milo oo lagu milo maaddooyinka firfircoon ee sunta cayayaanka, fududaynta habayntooda iyo codsigooda. Xalka caadiga ah waxaa ka mid ah xylene, toluene, benzene, methanol, iyo ether petroleum. Waxa ugu horrayn loo adeegsadaa samaynta fiirsashada emulsifiable (EC). Shuruudaha muhiimka ah waxaa ka mid ah awood kala diris xoog leh, suntan hoose, barta toosan ee sare, olol la'aanta, qiimo jaban, iyo helitaan ballaaran.
·Emulsifiers?
Mashiinnada dusha sare ee xasiliya kala firidhsanaanta dareere aan la qarin karin (tusaale, saliid) mid kale (tusaale, biyo) sida dhibco yar yar, samaynta emulsion aan muuqan ama badh-mudan. Kuwaas waxaa loo yaqaan emulsifiers. Tusaalooyinka caadiga ah waxaa ka mid ah esters-ku-saleysan polyoxyethylene ama ethers (tusaale, saliidda castor polyoxyethylene ether, alkylphenol polyethylene ether), saliid cas ee Turkiga, iyo sodium dilaurate diglyceride. Waxaa si weyn loogu isticmaalaa xoogga emulsifiable, hababka biyaha-emulsion, iyo microemulsions.
·Kala firdhiyey?
Surfactants ee loo isticmaalo qaababka sunta cayayaanka si looga hortago isu geynta walxaha adag ee hababka kala firidhsan dareeraha adag, hubinta ka joojinta labiskooda muddada dheer ee dareeraha. Tusaalooyinka waxaa ka mid ah sodium lignosulfonate iyo NNO. Waxa ugu horrayn loo isticmaalaa soo saarista budada la qoyan karo, granules-ka biyaha la firdhi karo, iyo joojinta biyaha.
