Focus on Cellulose ethers

Tšebeliso ea Daily Chemical Grade Hydroxypropyl Methyl Cellulose (HPMC) ho Hlatsoa Lik'hemik'hale Tsa Letsatsi le Letsatsi

K'hemik'hale ea letsatsi le letsatsi ea hydroxypropyl methylcellulose ke polymer ea maiketsetso e entsoeng ka selulose ea tlhaho ka phetoho ea lik'hemik'hale. Cellulose ether e tsoa ho cellulose ea tlhaho. Tlhahiso ea cellulose ether e fapane le li-polymers tsa maiketsetso. Thepa ea eona ea mantlha ke cellulose, motsoako oa tlhaho oa polymer.

Ka lebaka la sebopeho sa cellulose ea tlhaho, selulose ka boeona ha e na matla a ho sebetsana le li-etherification agents. Leha ho le joalo, ka mor'a ho phekoloa ha moemeli oa ho ruruha, maqhama a matla a hydrogen pakeng tsa liketane tsa molek'hule le liketane li senyeha, 'me ho lokolloa ka mafolofolo ha sehlopha sa hydroxyl ho fetoha selulose e sebetsang ea alkali. Kamora karabelo ea etherifying agent, sehlopha sa -OH se fetoloa sehlopha OR Fumana cellulose ether. 200,000-viscosity hydroxypropyl methylcellulose bakeng sa "Max" letsatsi le leng le le leng la lik'hemik'hale tsa lik'hemik'hale ke phofo e tšoeu kapa e mosehla hanyenyane, e se nang monko, e sa latsoeheng ebile e se chefo. E ka qhibiliha ka metsing a batang le motsoako o tsoakiloeng oa lintho tse phelang ho etsa tharollo e hlakileng ea viscous.

Mokelikeli o sebelisoang ke metsi o na le ts'ebetso ea holim'a metsi, pepeneneng e phahameng, botsitso bo matla, 'me ha o amehe ke pH ha o qhibiliha metsing. E na le liphello tse teteaneng le tse thibelang ho hatsela ho li-shampoo le li-gels tsa shaoara, 'me e na le ho boloka metsi le thepa e ntle ea ho etsa filimi bakeng sa moriri le letlalo. Ka ho phahama ho hoholo ha lisebelisoa tsa mantlha, tšebeliso ea cellulose (antifreeze thickener) ka shampoo le gel ea shaoara e ka fokotsa litšenyehelo haholo mme ea fihlela phello e lakatsehang.
