IBanga loKwakha iBanga le-HPMC lokuzilinganisa ngokwalo

I-HPMC, okanye i-Hydroxypropyl Methylcellulose, i-ether ye-cellulose esetyenziswa kakhulu kushishino lokwakha.Isetyenziswa ngokuqhelekileyo njengesongezo kwi-self-leveling compounds, izinto ezisetyenziselwa ukulinganisa imigangatho engalinganiyo okanye ukudala indawo egudileyo kwezinye izinto zomgangatho.

Iikhompawundi zokuzilinganisa zihlala zisetyenziswa kwiiprojekthi zokwakha ukulinganisa imigangatho engalinganiyo okanye enamabala aphantsi.Ezi khompawundi zenziwa ngokudityaniswa kwesamente, isanti, kunye nezinye izinto, kwaye zixutywe namanzi ukwenza ulwelo olugalelayo.Nje ukuba igalelwe emgangathweni, i-self-leveling compound iyahamba ukuze idale umphezulu ogudileyo, othe tyaba.

I-HPMC isoloko yongezwa kwiikhompawundi zokuzilinganisa ukuphucula ukusebenza kwazo.Ngokukodwa, kunceda ukuphucula ukusebenza kwe-compound, okwenza kube lula ukuthulula kunye nokusabalalisa ngokulinganayo.Kwakhona kunceda ukunciphisa i-shrinkage kunye nokuqhekeka ngexesha lokumisa, kwaye kunokuphucula amandla okubambisana phakathi kwe-compound kunye ne-substrate ephantsi.

Ibakala lokwakha i-HPMC luhlobo oluthile lwe-HPMC eyilelwe ukusetyenziswa kwizicelo zokwakha.Ihlala isetyenziswa kwiikhompawundi zokuzilinganisa, kunye nakwezinye izinto zokwakha ezifana nodaka, i-grouts, kunye ne-stuccos.

Iipropati ezithile zebakala lokwakha i-HPMC inokwahluka ngokuxhomekeke kwimveliso kunye nomvelisi, kodwa ngokubanzi, inezi mpawu zilandelayo:

Ukugcinwa kwamanzi aphezulu: I-HPMC yimathiriyeli ye-hydrophilic, ethetha ukuba inobudlelwane obuqinileyo bamanzi.Le propati inceda ukuphucula ukusebenza kwee-self-leveling compounds, njengoko inceda ukugcina umxube omanzi kwaye kulula ukusasazeka.

Isakhono esihle sokwenza ifilim: I-HPMC inokwenza ifilimu ebhityileyo kumphezulu wekhompawundi ezizilinganisayo njengoko isoma, enceda ekuphuculeni amandla ayo oomatshini kunye nokuqina.

Ukubambelela okuphuculweyo: I-HPMC inokuphucula ukubambelela kwikhompawundi yokuziphakamisa kwi-substrate engaphantsi, inceda ukudala indawo eyomeleleyo, ehlala ixesha elide.

Ukunciphisa ukuncipha kunye nokuqhekeka: I-HPMC inokunceda ukunciphisa inani le-shrinkage kunye nokuqhekeka okwenzeka ngexesha lokumisa, oku kunokukhokelela kwindawo engaphezulu kwaye egudileyo.

Non-ityhefu kunye nobungane kokusingqongileyo: HPMC kuyinto non-ityhefu, imathiriyeli enobuhlobo kokusingqongileyo ekhuselekileyo ukusetyenziswa kwizicelo zokwakha.

Xa usebenzisa iikhompawundi self-leveling equlathe grade ulwakhiwo HPMC, kubalulekile ukulandela imiyalelo umenzi ngononophelo.Umxube kufuneka ulungiswe ngokuhambelana nomlinganiselo ocetyiswayo wamanzi ukuya kumgubo, kwaye kufuneka uxutywe ngokucokisekileyo ukuqinisekisa ukuba i-HPMC isasazwa ngokulinganayo kuwo wonke umxube.

Emva kokuba i-self-leveling compound igalelwe emgangathweni, kufuneka isasazwe ngokusebenzisa i-trowel okanye esinye isixhobo ukwenza umphezulu olinganayo.Kubalulekile ukusebenza ngokukhawuleza, njengoko i-compound iya kuqala ukuseta ngexesha elifutshane.

Emva kokuba i-compound isasaziwe, kufuneka ishiywe ukuze yome ixesha elicetyiswayo ngaphambi kokuba kufakwe izinto ezongezelelweyo zomgangatho.Oku kuya kunceda ukuqinisekisa ukuba umphezulu uphiliswe ngokupheleleyo kwaye ulungele ukusetyenziswa.

Ngokubanzi, ibakala lokwakha i-HPMC sisixhobo esibalulekileyo kushishino lokwakha, ngakumbi kuphuhliso lweekhompawundi zokuzilinganisa.Iimpawu zayo ezikhethekileyo zinceda ekuphuculeni ukusebenza kwezi zinto, okwenza kube lula ukusebenza kunye nokuqina ngakumbi ngexesha.Ngokusebenzisa i-self-leveling compounds equlethe i-HPMC, iingcali zokwakha zinokwenza imiphezulu egudileyo, inqanaba elifanele uluhlu olubanzi lwezinto zomgangatho.
