I-Hydroxypropyl methylcellulose (HPMC) iyikhompawundi esetyenziswa kakhulu kwishishini lokwakha, ngokukodwa kwi-tile yokunamathelisa i-tile. Le polymer eguquguqukayo enyibilikayo yamanzi inoluhlu olubanzi lweepropathi, iyenza isithako esidumileyo kwizinto zokuncamathelisa, iingubo kunye nezinye iikhemikhali zokwakha.
Intshayelelo ngeHydroxypropyl Methylcellulose (HPMC)
I-Hydroxypropyl methylcellulose (HPMC) i-non-toxic, i-organic, i-polymer e-soluble yamanzi esetyenziswa kakhulu kwishishini lokwakha. Iphuma kwi-cellulose, i-polymer yendalo efumaneka kwimithi kunye nezinye izinto zezityalo. I-HPMC iguqulwa ngokwekhemikhali ngokongeza i-hydroxypropyl kunye namaqela e-methyl kumqolo we-cellulose, ngaloo ndlela iphucula ukugcinwa kwamanzi, ukujiya kunye neempawu zokunamathela.
I-HPMC yipolymer eguquguqukayo enokuthi ilungiselelwe iimfuno ezithile zemveliso. Ifumaneka kumabanga ahlukeneyo, ukusuka ezantsi ukuya kwi-viscosity ephezulu, kwaye inokwenziwa ngokwezifiso ngamanqanaba ahlukeneyo e-hydroxypropyl kunye ne-methyl substitution. Oku kuvumela abavelisi ukuba bahlengahlengise iimpawu zokusebenza kweemveliso zabo, zizenze zisebenze ngakumbi, kulula ukuzisebenzisa kwaye zingabizi kakhulu ukuvelisa.
Izinto ezilungileyo ze-HPMC kwi-adhesives tile
I-HPMC isetyenziswa ngokubanzi kwiindlela zokuncamathelisa iithayile ngenxa yeenzuzo zayo ezininzi. Nazi ezinye izizathu zokuba kutheni i-HPMC iyipolymer yokhetho lokuncamathelisa iithayile:
1. Ukugcinwa kwamanzi
I-HPMC inokufunxa kwaye igcine izixa ezikhulu zamanzi, iyenza ibe yeyona arhente ibalaseleyo yokugcina amanzi kwiintambo zokuncamathelisa iithayile. Oku kubalulekile kuba amanzi anceda ukwenza i-adhesive isebenze kwaye idibanise kwi-substrate. Nge-HPMC, i-adhesive ye-tile ihlala isebenza ixesha elide, enika i-installer ixesha elingakumbi lokusebenzisa i-adhesive kunye nokulungelelanisa i-tile ngaphambi kokuba ibeke.
2. Ukutyeba
I-HPMC yi-thickener eyenza izinto zokuncamathelisa iithayile zibonakale ngakumbi, zinceda ekuphuculeni amandla abo okubopha. I-HPMC ityebisa isincamathelisi ngokubambisa iimolekyuli zamanzi, ezityebisa isincamathelisi kwaye zenze intlama ehambelana ngakumbi. Oku kwenza kube lula ukusebenzisa i-adhesive ngokulinganayo kwaye kunciphisa umngcipheko wokuqhekeka komlomo (oko kukuthi ukungalingani phakathi kweetayile).
3. Ukuphucula ukubambelela
I-HPMC iphucula i-adhesive of adhesives tile ngenxa yeempawu zayo zokubambelela. Xa ifakwe kwi-adhesive, i-HPMC yenza ifilimu encinci kumphezulu we-substrate enceda ukudibanisa i-adhesive kwi-tile. Ifilimu iphinda ithintele i-adhesive ukuba yome ngokukhawuleza, ibangele ukuba ilahlekelwe amandla okudibanisa.
4. Ukuba bhetyebhetye
I-HPMC inokwenza izinto zokuncamathelisa iithayile zibe bhetyebhetye, nto leyo ibalulekileyo kwiindawo ezihamba rhoqo, njengakwizakhiwo ezihlala okanye ezifumana iinyikima okanye iinyikima. I-HPMC inceda ukwenza i-adhesive i-elastic ngakumbi, ivumela ukuba iguquke kwaye ihambe kunye nesakhiwo, inciphisa umngcipheko wokuqhekeka kweethayile okanye ukuwa.
5. Ipropati ye-Anti-sag
HPMC inceda ukunciphisa umngcipheko wokuncamathelisa ithayile eludongeni. Ngenxa yeepropathi zayo ezityebileyo, i-HPMC inceda ukuthintela ukuncamathelisa ekutyibilikeni okanye ekujikeni eludongeni phambi kokuba kumiswe. Oku kunokunceda abafakeli bafezekise ukufakela kwethayile okuhambelana ngakumbi kunye nokunciphisa isidingo sokuphinda kusetyenzwe kwakhona.
ukuququmbela
I-HPMC yipolymer eguquguqukayo ebonelela ngeenzuzo ezininzi kushishino lokwakha, ngakumbi kwiinkqubo zokuncamathelisa iithayile. Ukugcina amanzi, ukuqina, ukubopha, ukuguquguquka kunye neempawu ezichasene ne-sag zenza ukuba ibe yinto ekhethiweyo phakathi kweengcali zokwakha kwihlabathi jikelele. Ngokusebenzisa i-HPMC ukulungisa kakuhle iimpawu zokusebenza zokuncamathelisa iithayile, abavelisi banokwenza i-adhesives ekulula ukuyisebenzisa, ibe nebhondi eqinile, ikwazi ukumelana nokufuduka kunye nokuxhathisa kwamanzi, kwaye ayinakwenzeka ukuba ingaphumeleli. Akumangalisi ke ngoko ukuba i-HPMC licandelo elibalulekileyo kushishino lokwakha lwanamhlanje.
