Selulose ea Hydroxyethyl (HEC)
Selulose ea Hydroxyethyl(HEC)
CAS:9004-62-0
Selulose ea Hydroxyethyl(HEC) ke ether ea cellulose e qhibilihang metsing e seng ea ionic, e sebelisoang e le setenya, colloid e sireletsang, sesebelisoa sa ho boloka metsi le modifier ea rheology lits'ebetsong tse fapaneng joalo ka pente e thehiloeng metsing, thepa ea kaho, lik'hemik'hale tsa oli le lihlahisoa tsa tlhokomelo ea motho ka mong. Ka lebaka la thepa ea eona e ikhethang, joalo ka ho qhibilihisa ho hoholo, ho qhibiliha metsing a chesang le a batang, le botsitso ba lik'hemik'hale, HEC ke motsoako oa bohlokoa lihlahisoa tse ngata tsa indasteri le tsa bareki.
HEC e hlahisoa ka ho hlahisa lihlopha tsa hydroxyethyl (-CH₂CH₂OH) ka har'a ketane ea polymer ea cellulose ka karabelo ea etherification. Phetoho ena e ntlafatsa ho qhibiliha ha eona metsing, bokhoni ba ho teteana, le ho lumellana le mefuta e fapaneng ea metsoako.

Melemo ea Bohlokoa:
1. Ho Boloka Metsi ka Botle: Ho thusa ho thibela ho oma pele ho nako dihlahisweng le ditlolong tse entsweng ka samente.
2. E Tsitsitse ho Pholletsa le Mefuta e Meholo ea pH: E lula e sebetsa libakeng tse nang le asiti, tse sa nke lehlakore le tse nang le alkaline.
3. Ha e na Ionic ebile e lumellana le eona: E sebetsa hantle le lik'hemik'hale tse fapaneng, ho kenyeletsoa le letsoai, li-surfactant le li-polymer tse ling.
4. E Ntlafatsa Tshebetso ya Sehlahiswa: E ntlafatsa botenya, ho kgomarela, ho etsa filimi le thepa ya ho kopanya.
5. E Bolokehile Tikolohong ebile e Bola: E tsoa ho cellulose, HEC ha e na chefo ebile e bola habonolo.
6. E Ntlafatsa Rheology le Litšobotsi tsa Phallo: E lumella ho viscous e laoloang, e thibela ho rotha, ho thella le karohano ea mekhahlelo.
Sephutheloana:
Sehlahisoa sa HEC se pakiloe ka mokotleng oa pampiri o nang le mekhahlelo e meraro ka mokotla oa polyethylene o ka hare o matlafalitsoeng, boima ba 'nete ke 25kg ka mokotla.
Polokelo:
E boloke ka tlung e pholileng e ommeng, hole le mongobo, letsatsi, mollo, pula.
KIMA Chemical Co., Ltd. ke moetsi oa litsebi ea ikhethang ka tlhahiso ea li-ether tsa cellulose, ho kenyeletsoa HydroxyethylSelulose(HEC). Ka bokgoni ba tlhahiso ba ditone tse 20,000 ka selemo, KIMA Chemical e fana ka mefuta e fapaneng ya dihlahiswa tsa HEC tsa boleng bo hodimo tlasa letshwao la KimaCell®, tse sebeletsang diindasteri tse fapaneng tse kang tsa kaho, dipente le dikobo, meriana le tlhokomelo ya motho ka mong.
