Dispersant waa nooc ka mid ah wakiilka firfircoon ee isdhexgalka, kaas oo leh lipophilic iyo sifooyinka hydrophilic ee molecules. Waxay kala firdhi kartaa qaybo adag oo dareere ah oo ah midabada aan organic iyo organic kuwaas oo ay adag tahay in ay ku milmaan dareeraha, ka hortagto wasakhowga iyo uumiga, oo waxay sameeyaan laba nooc oo reagents philophile ah oo loo baahan yahay ka joojinta xasilloon.Wakiilka kala firdhiya MF

Surfactant A waa walax si weyn u yarayn karta xiisadda dusha sare ee xalka bartilmaameedka. Waxay leedahay koox saliideed hydrophilic go'an oo lagu jihayn karo dusha sare ee xalka. Qaab dhismeedka molecular ee surfactants wuxuu leeyahay laba sifo: hal dhamaadka waa kooxda hydrophilic, dhamaadka kale waa kooxda hydrophobic; Kooxaha hydrophilic sida caadiga ah waa kooxaha polar, sida sulfonic acid, karboksylic acid, sulfuric acid, amino ama kooxaha amin iyo cusbada ay, kooxaha amide, kooxaha hydroxyl, ether bonds, iwm, sidoo kale loo isticmaali karaa sida kooxaha hydrophilic polar; Kooxaha Hydrophobic inta badan waa silsilado kaarboon-carbon ah oo aan polar ahayn, sida kuwa leh in ka badan 8 atamka kaarboon. Surfactants waxay u kala qaybsan yihiin surfactants ionic (oo ay ku jiraan cationic surfactants iyo anionic surfactants), surfactants composite, surfactants amphoteric, surfactants non-ion, surfactants kale iyo wixii la mid ah.

Sidee kala firdhiyaashi u shaqeeyaan!

Wakiilka kala firdhiya MFaaminsan in qof kasta oo aan la aqoon, waxaan ka hadalnay wax badan oo ku saabsan hortoodaWakiilka kala firdhiya MFmacluumaadka, haddaba waa maxay mabda'a shaqada ee kala firdhinta? Haddii aadan weli aqoon u lahayn aqoontan, waxaan si wadajir ah u baran karnaa mabda'a shaqada ee kala firdhinta!

Mabda'a kala firdhisan:

1, nuugo dusha sare ee qaybaha adag, yaraynta xiisadda dusha sare ee dareeraha - dareeraha ama dareeraha adag. Dusha sare ee qaybaha adag ee adag waa sahlan tahay in la qoyo.

2, wax polymer ah nooca kala firdhiso, oogada sare ee qaybaha adag waxay soo saaraan lakabka adsorption, si ay kharashka dusha sare ee qaybaha adag kordho, hagaajinta xoog dib u soo celinta u dhexeeya qayb ka mid ah xannibaad saddex-cabbir ah.

3, samee dusha sare ee qaybaha adag waxay soo saaraan qaab dhismeedka lakabka qaabdhismeedka labajibbaaran, dusha sare ee kala firdhiyo wanaagsan iyo kuwa xunba waxay leeyihiin xiriir adag oo biyo ah, hagaajinta heerka walxaha adag ee qoyan biyaha. Dhexda walxaha adkaha ah waxaa ka fogaanaya dib-u-celinta koronto-dhaliyaha.

4, ka dhig nidaamka maamulka summetrical, sifooyin sabeynaya, ma dhigid, si dhammaan nidaamka maamulka sifooyinka kiimikada organic. Xagga sare, codsiga kala firdhiya waxay si deggan u kala firdhi kartaa qaybo adag oo ku jira xaaladda dareeraha ah.
