Li-cellulose ethers ke li-additives tsa bohlokoa lihlahisoa tsa samente ka lebaka la ho tiea ha tsona, ho boloka metsi le ho fetola li-viscosity.Taolo e nepahetseng ea thepa ea eona ke ea bohlokoa ho netefatsa boleng ba lihlahisoa tsa samente.Tse latelang ke litsela tse sebetsang tsa ho laola thepa ea cellulose ethers lihlahisoa tsa samente.
1. Khetha ether ea cellulose e loketseng
Mohato oa pele oa ho laola thepa ea cellulose ether ke ho khetha mofuta oa cellulose ether e loketseng bakeng sa tšebeliso e reriloeng.Ho na le mefuta e fapaneng ea li-cellulose ethers 'marakeng, joalo ka methylcellulose (MC), hydroxyethylcellulose (HEC), hydroxypropylmethylcellulose (HPMC), le carboxymethylcellulose (CMC).Mofuta o mong le o mong o na le litšobotsi tse ikhethang tse etsang hore o tšoanelehe bakeng sa lits'ebetso tse ikhethileng.Ka mohlala, MC e loketse lirafshoa le li-plaster, ha HPMC e loketse li-grouts le li-adhesives tsa lithaele.Ka hona, mofuta o nepahetseng oa cellulose ether o tlameha ho khethoa bakeng sa ts'ebeliso e reriloeng.
2. Laola boleng ba cellulose ether
Boleng ba cellulose ether bo na le tšusumetso e kholo ho thepa ea eona.Ka hona, ho bohlokoa ho etsa bonnete ba hore li-cellulose ethers li fihlela litekanyetso tse hlokahalang tsa boleng.Boleng ba cellulose ethers bo ka laoloa ka ho shebella viscosity ea eona, mongobo le lintho tse ling tsa 'mele.Hape ke habohlokoa ho etsa bonnete ba hore li-cellulose ethers ha li na litšila le litšila tse ka amang ts'ebetso ea tsona.
3. Mekhoa e nepahetseng ea ho kopanya
Li-cellulose ethers li hloka ho tsoakoa hantle le lihlahisoa tsa samente ho netefatsa ho hasana le ts'ebetso ea tsona e nepahetseng.Ts'ebetso ea ho kopanya e lokela ho etsoa ho sebelisoa lisebelisoa le mekhoa e nepahetseng ea ho etsa bonnete ba hore li-cellulose ethers li ajoa ka ho lekana ho pholletsa le matrix a samente.Mokhoa oa ho kopanya o lokela ho ba butle le butle-butle ho thibela ho thehoa ha maqeba le ho etsa bonnete ba ho hasana ka ho feletseng ha li-cellulose ethers.
4. Tekanyo e nepahetseng
Tekanyo ea cellulose ether e bohlokoa ho laola thepa ea eona lihlahisoa tsa samente.Palo e nepahetseng ea cellulose ether e itšetlehile ka ts'ebeliso e khethehileng le mofuta oa cellulose ether e sebelisitsoeng.Tekanyo e lokela ho khethoa ho latela thepa ea rheological ea lihlahisoa tsa samente.Tekanyo e feteletseng kapa e sa lekaneng ea cellulose ether e tla ama ts'ebetso ea lihlahisoa tsa samente.
5. Teko le Tlhokomelo
Ho etsa liteko le ho beha leihlo tšebetso ea li-cellulose ethers lihlahisoa tsa samente ho bohlokoa ho netefatsa boleng ba tsona le katleho ea tsona.Thepa ea cellulose ethers e ka lekoa ho sebelisoa mekhoa e fapaneng, joalo ka litekanyo tsa rheological, ho beha liqeto tsa nako, liteko tsa matla a hatellang, le liteko tsa ho boloka metsi.Tlhokomelo ea kamehla ea ts'ebetso ea cellulose ethers lihlahisoa tsa samente e ka thusa ho tseba mathata leha e le afe le ho nka khato ea ho lokisa.
Ho laola thepa ea cellulose ethers lihlahisoa tsa samente ho bohlokoa ho netefatsa boleng ba tsona le katleho ea tsona.Khetho ea li-cellulose ethers tse loketseng, ho laola boleng ba tsona, mekhoa e nepahetseng ea ho kopanya, tekanyo e nepahetseng, le ho hlahloba le ho hlahloba ke mekhoa e sebetsang ea ho laola ts'ebetso ea li-cellulose ethers lihlahisoa tsa samente.Ka ho latela litataiso tsena, ts'ebetso e nepahetseng le boleng ba cellulose ethers lihlahisoa tsa samente li ka netefatsoa.
