Ma taqaanaa noocyada daawooyinka sunta cayayaanka ee jira?

Daawooyinka lagu daweeyo cayayaanka waa walxo kaaliyeyaal ah oo lagu daro inta lagu jiro farsamaynta ama codsiga qaacidooyinka cayayaanka si loo hagaajiyo sifooyinkooda kiimikada jirka, oo sidoo kale loo yaqaan kaabayaasha cayayaanka. In kasta oo kaabayaasha laftoodu guud ahaan aysan lahayn wax dhaqdhaqaaq bayooloji ah ama aan lahayn, haddana waxay si weyn u saameyn karaan waxtarka xakamaynta cayayaanka. Iyada oo la adeegsanayo iyo horumarinta baahsan ee kaabayaasha cayayaanka, noocyadooda ayaa sii waday inay sii fidaan, taasoo ka dhigaysa xulashada kaaliyaha saxda ah caqabadda labaad ee ugu weyn beeraleyda ka dib marka ay doortaan cayayaanka laftooda.

1.Kaaliyeyaasha Ka Caawiya Kala-firdhinta Maaddooyinka Firfircoon​

· Buuxiyaasha iyo Sideyaasha​

Kuwani waa macdan adag oo aan firfircoonayn, walxo ku salaysan dhir, ama walxo macmal ah oo lagu daray inta lagu jiro habaynta qaacidooyinka sunta cayayaanka adag si loo hagaajiyo isku-darka badeecada kama dambaysta ah ama loo hagaajiyo xaaladdeeda jireed. Buuxiyeyaashu waxaa loo isticmaalaa in lagu khafiifiyo maaddada firfircoon oo lagu xoojiyo kala firdhisteeda, halka kuwa sideyaashu ay sidoo kale u adeegaan inay nuugaan ama qaadaan qaybaha waxtarka leh. Tusaalooyinka caadiga ah waxaa ka mid ah dhoobada, dhulka diatomaceous, kaolin, iyo dhoobada dhoobada.

Buuxiyeyaashu badanaa waa walxo aan dabiici ahayn oo dhexdhexaad ah sida dhoobada, dhoobada dhoobada, kaolin, dhulka diatomaceous, pyrophyllite, iyo budada talcum. Shaqadooda ugu weyni waa inay khafiifiyaan maaddada firfircoon oo ay nuugaan. Waxaa inta badan loo isticmaalaa soo saarista budada, budada qoyan, granules, iyo granules-ka biyaha ku milma. Isku-darka cayayaanka iyo bacriminta cayayaanka ee hadda caanka ah. (ama "bacriminta daawada") waxay u isticmaalaan bacrimiyeyaasha sidii xambaarro sunta cayayaanka, iyagoo isku daraya labada si loo gaaro codsi mideysan.

​Sideyaasha ma aha oo kaliya in la khafiifiyo walaxda firfircoon laakiin sidoo kale waxay ka caawisaa nuugista, iyadoo door muhiim ah ka ciyaareysa xasilloonida qaacidada.

·Dareeraha​

Walxaha dabiiciga ah ee loo isticmaalo in lagu milo laguna khafiifiyo maaddooyinka firfircoon ee sunta cayayaanka, taasoo sahlaysa habayntooda iyo codsigooda. Waxyaabaha dareeraha ah ee caadiga ah waxaa ka mid ah xylene, toluene, benzene, methanol, iyo petroleum ether. Waxaa ugu horreyn loo isticmaalaa qaabaynta isku-darka emulsifiable (EC). Shuruudaha muhiimka ah waxaa ka mid ah awood milmi karta oo xooggan, sunta oo yar, dhibic iftiin oo sareysa, aan guban karin, kharash yar, iyo helitaan ballaaran.

·Emulsifiers​

Waxyaabaha dul-saarayaasha ah ee xasiliya kala-baxa hal dareere aan la misi karin (tusaale, saliid) una beddela mid kale (tusaale, biyo) iyagoo ah dhibco yaryar, iyagoo samaynaya emulsion aan muuqan ama nus-opaque ah. Kuwaas waxaa loo yaqaan emulsifiers. Tusaalooyinka caadiga ah waxaa ka mid ah esters-ka ku salaysan polyoxyethylene ama ethers (tusaale, saliidda castor polyoxyethylene ether, alkylphenol polyethylene ether), saliidda cas ee Turkiga, iyo sodium dilaurate diglyceride. Waxaa si weyn loogu isticmaalaa isku-darka emulsifiable, qaacidooyinka emulsion-ka biyaha, iyo microemulsions.

·Kala-baxayaal​

Waxyaabaha loo yaqaan "surfactants" ee loo isticmaalo qaab-dhismeedka sunta cayayaanka si looga hortago isku-darka walxaha adag ee nidaamyada kala-fidinta dareeraha adag, iyagoo hubinaya in muddo dheer ay si siman ugu shaqeeyaan dareerayaasha. Tusaalooyinka waxaa ka mid ah sodium lignosulfonate iyo NNO. Waxaa ugu horreyn loo isticmaalaa soo saarista budada qoyan, granules-ka biyaha ku milma, iyo suspension-ka biyaha.
