HPMC (ke hore, hydroxypropyl methylcellulose) ke motsoako oa bohlokoa tlhahisong ea li-adhesive tsa lithaele.E ntlafatsa ho khomarela, ho sebetsa le ho boloka metsi a li-adhesive tsa lithaele.Sehloohong sena, re tla u fa tataiso e felletseng ea ho sebelisa HPMC lits'ebetsong tsa sekhomaretsi sa lithaele.
1. Selelekela ho HPMC
HPMC ke non-ionic cellulose ether e fumanoang ka ho fetola selulose ea tlhaho.Mokhoa oa ho etsa tlhahiso o kenyelletsa ho phekola cellulose ka alkali ho e qhaqha, ebe o eketsa methyl chloride le propylene oxide ho e fetola.Sephetho ke phofo e tsoeu kapa e bosoeu e qhibilihang habonolo metsing.
2. Litšobotsi tsa HPMC
HPMC ke polymer e sebetsang haholo e nang le thepa e mengata e ikhethang.Tse ling tsa likarolo tsa eona tsa bohlokoa li kenyelletsa:
- Ho boloka metsi hantle
- ho khomarela holimo
- Matla a ntlafalitsoeng
- Ntlafatso ea khanyetso ea sag
- Khanyetso e matlafalitsoeng ea ho thella
- ho tsamaea hantle
- Lihora tsa ho bula tse ntlafalitsoeng
3. Melemo ea HPMC ts'ebelisong ea sekhomaretsi sa lithaele
Ha e sebelisoa tlhahiso ea sekhomaretsi sa lithaele, HPMC e fana ka melemo e mengata ho kenyelletsa:
- Ho boloka metsi ho betere bakeng sa ts'ebetso e ntlafalitsoeng ea sekhomaretsi sa lithaele libakeng tse metsi
- Mehaho e ntlafalitsoeng ea sekhomaretsi ho netefatsa hore lithaele li ts'oaroa hantle
- Machability e ntlafalitsoeng e netefatsa hore ts'ebeliso e bonolo ebile e fokotsa boikitlaetso bo hlokahalang ho fihlela sebaka se boreleli
- E fokotsa ho honyela le ho thella, e ntlafatsa botle ba bokaholimo ba lithaele
- E ntlafatsa botsitso ba likhomaretsi tsa lithaele, e khothaletsa ts'ebeliso e ts'oanang le e nepahetseng
- Khanyetso e ntlafalitsoeng ea ho thella bakeng sa polokeho e eketsehileng holim'a lithaele
4. Tšebeliso ea HPMC ho Likopo tsa Tile Adhesive
HPMC e sebelisoa e le sekhomaretsi, sekhomaretsi, se bolokang metsi le mofetoleli oa rheology lits'ebetsong tsa sekhomaretsi sa lithaele.Ka tloaelo e eketsoa ka 0.5% - 2.0% (w / w) ea motsoako o omileng kaofela.Ka tlase ke libaka tse ling tsa bohlokoa tsa ho sebelisa HPMC.
4.1 Ho boloka metsi
Sekhomaretsi sa lithaele se hloka ho siuoa se tiile e le hore se kenyang se be le nako e lekaneng ea ho lokisa tile.Tšebeliso ea HPMC e fana ka mokhoa o babatsehang oa ho boloka metsi le ho thibela sekhomaretsi ho omisa kapele haholo.Ho boetse ho bolela hore sekhomaretsi ha se hloke ho khutlisetsoa metsi, se ka lebisang ts'ebetsong e sa tsitsang.
4.2 Ntlafatsa ho khomarela
Thepa ea sekhomaretsi ea HPMC e ntlafatsa haholo matla a maqhama a likhomaretsi tsa lithaele.E thusa ho etsa bonnete ba hore tile e lula e sireletsehile sebakeng seo, esita le libakeng tse phahameng tsa sephethephethe kapa libakeng tse metsi.
4.3 Ho khona ho sebetsa
HPMC e ntlafatsa ts'ebetso ea likhomaretsi tsa lithaele, e etsa hore ho be bonolo ho e sebelisa le ho fihlela sebaka se boreleli.E etsa hore sekhomaretsi se be bonolo ho kama, ho fokotsa boiteko bo hlokahalang ho sutumelletsa sekhomaretsi holim'a metsi.
4.4 Fokotsa ho honyela le ho putlama
Ha nako e ntse e ea, sekhomaretsi sa lithaele se ka honyela kapa sa senyeha, se fella ka qetello e sa thabiseng le e sa sireletsehang.Tšebeliso ea HPMC e fokotsa haholo ho honyela le ho thella, ho etsa bonnete ba hore ho na le sephetho se setle le se khahlisang.
4.5 Ntlafatsa khanyetso ea ho thella
Ho thella le ho oa ke kotsi e kholo holim'a lithaele, haholo ha li le metsi.Khanyetso e matlafalitsoeng ea ho thella ea HPMC e etsa hore likhomaretsi tsa lithaele li sebelisoe ka mokhoa o sireletsehileng le ho fokotsa kotsi ea ho thella le ho oa.
5. Mokhoa oa ho Sebelisa HPMC ka Tile Adhesive Applications
HPMC e atisa ho eketsoa ka tekanyo ea 0.5% - 2.0% (w / w) ea motsoako o omileng kaofela.E lokela ho kopanngoa pele le samente ea Portland, lehlabathe le phofo e meng e omeletseng le lisebelisoa tse ling pele o eketsa metsi.Ka tlase ke mehato e amehang ho sebeliseng HPMC lits'ebetsong tsa sekhomaretsi sa lithaele.
- Eketsa phofo e ommeng sejaneng se kopanyang.
- Eketsa HPMC ho motsoako oa phofo
- Hlohlelletsa motsoako oa phofo ho fihlela HPMC e ajoa ka ho lekana.
- Butle-butle eketsa metsi motsoakong ha u ntse u hlohlelletsa kamehla ho qoba likotola.
- Tsoela pele ho whisk ho fihlela motsoako o boreleli 'me o e-na le mokhoa o ts'oanang.
6. Qetello
HPMC ke motsoako oa bohlokoa tlhahisong ea likhomaretsi tsa lithaele, e fanang ka melemo ea bohlokoa joalo ka mamarelo a matlafalitsoeng, ts'ebetso e ntlafalitsoeng ea ts'ebetso, le ho honyela ho fokolang le ho fokotseha.Ho sebelisa HPMC lits'ebetsong tsa sekhomaretsi sa lithaele ho hloka motsoako o nepahetseng le litekanyetso bakeng sa liphetho tse nepahetseng.
Ka hona, re khothaletsa ka matla tšebeliso ea HPMC ha ho etsoa li-adhesives tsa lithaele ho thabela melemo ea eona le ho ntlafatsa boleng ba sebaka se phethiloeng.
