Kenyelletso ea HPMC le MHEC:
HPMC le MHEC ke li-celpe tsa celluulo tsa celluulo tse sebelisoang hangata tlung ea kaho, ho kenyelletsa le lefu la ho haha. Li-polymers tsena li nkiloe le Celluddlese, polymer ea tlhaho e fumanehang marakong a lifofane ea lema. Ha H o kenela hore omile motsoako oa li-HPMC le MHMC le MHEC e sebetsa e le li-thicker, metsi a bolokang thepa le ho ntlafatsa thepa le ho ntlafatsa liphetoho le ho ntlafatsa thepa.
1. Ho Boloka Metsi:
HPMC LE MHEC ke polyromilic polymers ea hydrophilic, ho bolelang hore ba na le moea o phahameng bakeng sa metsi. Ha ba kenya likelello tsa lefu la likerekeng tse omisang, ba etsa filimi e tšesaane ka holim'a likaroloana tsa samente, ba thibela mouoane kapele ka potlako nakong ea ho folisa. Hyrate ena e telele e eketsa ntlafatso ea matla a seretse, e fokotsa menyetla ea ho akheha 'me e tiisa thepa e nepahetseng.
2. Ntlafatsa liphetoho:
HPMC le mhec ntlafatsa melemo ea litlolo tse ommeng tsa ho omella ka ho hlahisa lubrication. Ba sebetsa joaloka polasetiki, ho fokotsa likhohlano lipakeng tsa likaroloana le ho nolofatsa ho kopanya, ho jala le ho qeta. Ho ba ntlafatso ena ho fella ka ho feto-fetoha le maemo le sa tloaelehang ha mokato oa sere se kentsoeng.
3. Eketsa lihora tsa ho qala:
Nako e bulehileng ke nako eo seretse se lulang e sa khone ho kopanya. HPMC le mhec o ile a holisa nako e bulehileng ea seriri se omileng ka ho fokotsa sekhahla sa mouoane oa metsi. Karolo ena e molemo haholo mererong e meholo ea kaho e hlokang linako tse hlokoang, joalo ka thapo kapa likopo tsa plaster.
4. Nchafatsa Khothatso:
Ho ba teng ha hpmc le mhec ka lithateng tse omeletseng bo khothalletsang khokahano e mengata ho kenyeletsa koncrete, le ceramic lithaelese. Polymis tsena li baka bokoko pakeng tsa seretse le substrate, ho ntlafatsa botshepehi ba botlalo le ts'ebetso ea lisebelisoa tse sebelisitsoeng. Ho feta moo, li fokotsa kotsi ea ho lieha ho khaotsa le ho arohana ha nako.
5. Ho senya:
Ho hlakoloa ke bothata bo tloaelehileng le seretse, haholo-holo maemong a omileng le ea ho hloma. HPMC LE MHEC Thusa ho fokotsa bothata bona ka ho ntlafatsa bompoli le maemo a ho fetoha le maemo a matrix ea mortar. Ka ho fokotsa shrinkage le ho laola ts'ebetso ea Heldration, polyers tsena li thusa ho ntlafatsa kotsi e akaretsang ea seretse se felileng, se felileng.
6. Ho fapanyetsana:
HPMC le MHEC ke lisebelisoa tse fapaneng tse ka sebelisoang ho mefuta e mengata ea lireschorente tse omileng ea kopanya. Hore na masonry a ipotse litsebi tsa masene, lisepa tsa tale. Liphetoho tsena li nolofatsa ts'ebetso ea ho etsa lihlahisoa 'me u li lumelle nts'etsopele ea tharollo ea tharollo ea seretse bakeng sa lits'ebetso tse itseng.
7. Melemo ea Tikoloho:
HPMC LE MHEC ke litlatsetso tse ntle tsa tikoloho tse tsoang lisebelisoa tse ncha tse nchafatsoang. Tšebeliso ea bona ka lefu la ho omisa ho thusa ho fokotsa lisebelisoa tsa tlhaho le ho fokotsa ho senya meloko, ka mokhoa o khothalletsang ntlafatso e tsitsitseng. Ho feta moo, bidmello ea bona e etsa biodegrame "e netefatsa tšusumetso ea tikoloho qetellong ea potoloho ea bophelo ba seretse.
HPMC LE MHEC e na le menyetla e mengata le ea bohlokoa ho lihlahisoa tsa seretse se fapaneng se ommeng. Ho tloha ho ntlafatsa ho ntlafatsa le ho futhumatsa ho hanyetsa ho ntlafatsa ts'ebetso ea bohlokoa ho ntlafatsa ts'ebetso ea bohlokoa ho ntlafatsa ts'ebetso ea bohlokoa le nako ea bophelo ba likotsi tsa kaho. Tse tsoang ho tsebiso e tšoarellang le tse ikhethileng, HPMC le MHEC lulang le khetho ea pele bakeng sa bahlahisi ba batla ho ntlafatsa ts'ebetso ea meaba ea seretse ha ba nyenyefatsa phello ea tikoloho.
