ukwazisa
Izongezo ziye zaba yinxalenye eqhelekileyo ye-adhesives tile kwaye zidlala indima ebalulekileyo ekusebenzeni kunye nokusebenza kwazo.Ukusetyenziswa kwezongezo kwi-adhesives ye-tile kubaluleke kakhulu kwishishini lokwakha lanamhlanje.Izongezo zinceda ukuphucula iimpawu zokuncamathelisa ezifana nokugcinwa kwamanzi, ukuqhubekeka kunye namandla ebhondi, okwenza ukuba zigcineke kwaye zisebenze.I-HPMC (i-Hydroxypropyl Methyl Cellulose) ngumzekelo wesongezo esisetyenziswa ngokuqhelekileyo kwishishini lokuncamathelisa iithayile.Eli nqaku lichaza iingenelo zokusebenzisa i-HPMC kwimveliso yokuncamathelisa iithayile.
Ziziphi ii-HPMCs?
I-Hydroxypropyl methylcellulose iphuma kwi-cellulose kwaye yenza umgubo omhlophe okanye okhanyayo ophuzi.Ayinatyhefu, ayinavumba kwaye inonyibiliko olubalaseleyo lwamanzi.I-HPMC ifunyenwe yi-hydrolysis yeentyantyambo zezityalo ukuvelisa i-cellulose, ethi ke iguqulwe ngokwekhemikhali ngokudibanisa amaqela e-methoxy kunye ne-hydroxypropyl kumakhonkco e-ether.Inyibilika emanzini, i-ethanol kunye ne-acetone kwaye ineempawu ezithile ze-organic and inorganic compounds.Isetyenziswa kakhulu kumashishini afana nokwakha, izithambiso, ukutya, amayeza kunye neengubo.
Iingenelo zokuSebenzisa i-HPMC kwii-Adhesives zeThayile
1. Ukuphucula ukugcinwa kwamanzi
Enye yeenzuzo eziphambili zokusebenzisa i-HPMC kwi-adhesives yethayile kukuba iphucula ukugcinwa kwamanzi.Ukugcinwa kwamanzi kubaluleke kakhulu kwinkqubo yokuvelisa i-adhesive njengoko iqinisekisa ukuba i-adhesive ihlala isebenza kwaye ayimiseli ngokukhawuleza.Xa i-HPMC yongezwa kwi-adhesive, idibanisa kunye neemolekyuli zamanzi ukwenza i-gel-like consistency.Ubume be-gel ye-HPMC buqinisekisa ukuba umxube wokubambelela uhlala umanzi kwaye uhambelana, ophucula ukuqhutyelwa kokubambelela kunye nokwandisa i-tile bonding.
2. Ukuphucula ukusebenza
Ukusetyenziswa kwe-HPMC kwi-adhesives ye-tile kuphucula ukusebenza, yindlela elula ngayo i-adhesive ixutywe, isetyenziswe kwaye ilungelelaniswe.I-machinability ibalulekile kwinkqubo yokuvelisa njengoko inquma ukusebenza kakuhle kwenkqubo yokufakela.Xa i-HPMC yongezwa kwi-adhesives, isebenza njenge-thickener, ebangela ukuhambelana okungcono kunye nokuphathwa okulula.Ukuhambelana okuphuculweyo kwe-adhesive kuqinisekisa ukuba kuhlala kuhambelana kwaye kunokubunjwa ngokulula, ukubunjwa okanye ukusabalalisa kwiindawo ezisemgangathweni ukuze zenze indawo epholileyo.
3. Ukwandisa amandla okudibanisa
Amandla ebhondi anqunywe yintambo phakathi kwe-substrate (i-tile) kunye ne-adhesive.Ukusebenzisa i-HPMC kwi-adhesives yethayile kwandisa amandla ebhondi ngokwandisa ibhondi phakathi kwethayile kunye ne-adhesive.Indima ye-HPMC kukunyusa indawo yoqhagamshelwano phakathi kwe-substrate kunye ne-adhesive.Olu qhagamshelwano luphuculweyo luphumela kwibhondi eyomeleleyo enokumelana noxinzelelo olukhulu kunye nobunzima.I-adhesion eyomeleleyo enikezelwa yi-HPMC iqinisekisa ukuba iileyile zihlala kwindawo nakwiindawo eziphezulu zezithuthi kwaye zihlala zixhathisa amandla omatshini.
4. Nciphisa ukushwabana
Njengoko i-adhesive yoma, iyancipha, idala izithuba kunye nezikhala phakathi kweetayile.Izikhewu kunye nezithuba zingabonakala zingabonakali kwaye zivumela ukufuma ukuba kungene, okunokubangela ukuba iithayile zixobuke.Ukusebenzisa i-HPMC kwi-adhesives ye-tile iqinisekisa ukuba i-adhesive yoma kancinane kwaye ngokulinganayo, ukunciphisa ukushwabana.Inkqubo yokomisa ngokukhawuleza ivumela ukuba i-adhesive ihlale, iqinisekisa ukuba i-tile nganye ibeka ngokulinganayo, ukunciphisa umngcipheko wezithuba ngenxa yokunciphisa.
5. Phucula ukumelana nemozulu
Ukusetyenziswa kwe-HPMC kwi-adhesives ye-tile kunokuphucula i-eatherability ye-adhesive.I-HPMC inikezela ngokhuseleko olongezelelweyo, iqinisekisa ukuba i-adhesive ihlala injalo nakwiimeko zemozulu ezinzima.Iimeko zangaphandle ezifana nokuguquguquka kweqondo lokushisa, ukufuma kunye nemvula kunokunciphisa i-adhesive bond kunye nokunciphisa ukusebenza kwayo.I-HPMC ibonelela ngengubo yokukhusela ekhusela i-adhesive kwiimeko zemozulu ezinzima, ukuqinisekisa ukuba ihlala isebenza ixesha elide.
ukuququmbela
Ukongeza i-HPMC kwi-adhesives ye-tile inika inzuzo ebalulekileyo, ukuphucula ukusebenza kwe-adhesive, ukusebenza, ukuzinza kunye namandla.Izibonelelo zibandakanya ukugcinwa kwamanzi okuphuculweyo, ukuqhubekeka okuphuculweyo, ukonyuka kokuqina kwebhondi, ukunciphisa ukucutheka kunye nokuphuculwa kwemozulu.Ezi ngenelo zinokuphucula umgangatho wezakhiwo ezihlala zikhuselekile kwaye zisebenza nakwimeko yemozulu embi.Ngenxa yeenzuzo ezininzi, ukusetyenziswa kwe-HPMC kwi-adhesives ye-tile ibe yinto eqhelekileyo yoshishino lokuvelisa i-tile.Ukuguquguquka kwayo kuyenze yathandwa kwaye yaba lolona khetho lokuqala lweengcali zokwakha kwihlabathi liphela
