HPMC – Umxube owomileyo wodaka

Yazisa:

Udaka lomxube owomileyo luyathandwa kushishino lokwakha ngenxa yokulula kokusetyenziswa, umgangatho ophuculweyo kunye nexesha elifanelekileyo.Izongezo ezahlukeneyo zidlala indima ebalulekileyo ekuphuculeni ukusebenza kodaka oluxubeneyo elomileyo, kwaye enye yezongezo ezaziwayo-kakuhle yi-hydroxypropyl methylcellulose (HPMC).Le polymer eguquguqukayo isetyenziswa ngokubanzi kumxube owomileyo wodaka ukunceda ukuphucula ukusebenza, ukuncamathela kunye nokusebenza kodaka ngokubanzi.

Ubume bemichiza kunye neempawu zeHPMC:

I-Hydroxypropylmethylcellulose iphuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo.Ubume bekhemikhali be-HPMC bubonakaliswa bubukho be-hydroxypropyl kunye namaqela e-methyl kumqolo we-cellulose.Esi sakhiwo sikhethekileyo sinikeza iipropati ezithile ze-HPMC, iyenza ilungele usetyenziso oluhlukeneyo kushishino lokwakha.

Iimpawu eziphambili zeHPMC ziquka:

Ugcino lwamanzi:

I-HPMC inomthamo ogqwesileyo wogcino lwamanzi, iqinisekisa ukuba udaka luhlala lusetyenziswa ixesha elide.Le propati ibalulekile ukukhusela udaka ukuba lome ngaphambi kwexesha kwaye luvumela ukusetyenziswa okungcono kwiindawo ezahlukeneyo.

Ukutyebisa amandla:

I-HPMC isebenza njenge-thickener kwaye inceda ukuphucula ukungaguquguquki kunye nokusebenza kodaka.Oku kuluncedo ngakumbi kwizicelo ezithe nkqo apho udaka lufuna ukunamathela kumphezulu ngaphandle kokuhexa.

Phucula ukuncamathela:

Ubukho be-HPMC buphucula ukunamathela kodaka kwii-substrates ezahlukeneyo, ukukhuthaza ukudibanisa okungcono kunye nokuqina kwesakhiwo sokugqibela. 

Seta ulawulo lwexesha:

Ngokuhlengahlengisa ngononophelo uhlobo kunye nobungakanani be-HPMC kwiresiphi yomxube owomileyo wodaka, ixesha lokumisela lodaka linokulawulwa.Oku kuvumela iiprojekthi zokwakha ukuba zibe bhetyebhetye kwaye zilungele iimfuno ezahlukeneyo kunye neemeko zokusingqongileyo.

Ukuguquguquka kunye nokumelana nokuqhekeka:

I-HPMC inika ukuguquguquka kodaka, ukunciphisa ukubakho kokuqhekeka kunye nokuphucula ukuqina ngokubanzi.Oku kubaluleke kakhulu kwizicelo apho isakhiwo sixhomekeke kumandla ashukumisayo okanye utshintsho lobushushu.

Ukusetyenziswa kwe-HPMC kudaka olomileyo oluxutyiweyo :

Ukuncamatheliswa kwethayile:

I-HPMC isetyenziswa ngokuqhelekileyo kwii-adhesives ze-tile ukuphucula ukubambelela, ukugcinwa kwamanzi kunye nokusebenza.I-polymer iqinisekisa ibhondi eqinile phakathi kwe-tile kunye ne-substrate, ngaloo ndlela ikwandisa ixesha elide le-tile surface.

Udaka lokutyabeka:

Kwiidaka zokutyabeka, i-HPMC inceda ukuphucula ukusebenza kunye nokunamathela komxube.Ipolymer inceda ukufezekisa i-plaster surface egudileyo kwaye ehambelanayo ngelixa unciphisa umngcipheko wokuqhekeka.

Udaka lwamatye:

I-HPMC isetyenziselwa udaka lwemasonry ukomeleza ugcino lwamanzi, ukusebenza kunye nokuncamathela.Iipropati eziphuculweyo zokudibanisa zenza izakhiwo ze-masonry zomelele kwaye zomelele ngakumbi.

Iikhompawundi zokuzilinganisa:

Ukugcina amanzi kunye neempawu ezityebileyo ze-HPMC zenza ukuba zilungele ukusetyenziswa kwiikhompawundi zokuzilinganisa.Ezi zixhobo ziqinisekisa umgangatho ogudileyo kwaye zingasetyenziselwa kwiimeko ezahlukeneyo zokwakha.

Isigcwalisi se-Seam:

I-HPMC ifakwe kwi-caulk ukuphucula ukuguquguquka kunye nokunamathela.Oku kubaluleke kakhulu kumalungu ahamba kunye nokwandiswa kwe-thermal.

Ulawulo lomgangatho kunye nokuhambelana:

Ukuqinisekisa umgangatho kunye nokuhambelana kwe-HPMC kwi-dry-mix mortar kubalulekile ukufezekisa ukusebenza okufunekayo.Amanyathelo okulawula umgangatho abandakanya iipolymers zokuvavanya iiparameters ezifana ne-viscosity, umxholo wokufuma kunye nokusabalalisa ubungakanani bamasuntswana.Izifundo zokuhambelana kufuneka ziqhutywe ukuvavanya intsebenziswano phakathi kwe-HPMC kunye nezinye izithako ekuqulunqweni kodaka ukuze kuqinisekiswe iziphumo ze-synergistic ngaphandle kokusabela okubi.

Iingqwalasela zokusingqongileyo:

I-HPMC ithathwa njengenobuhlobo nokusingqongileyo njengoko ivela kwimithombo ehlaziyekayo.I-biodegradability ye-HPMC iqinisekisa ukuba ukusetyenziswa kwayo kwizicelo zokwakha akuyi kuba nempembelelo yexesha elide kwindalo esingqongileyo.

ukuququmbela:

IHydroxypropyl methylcellulose sisongezo esisebenza ngeendlela ezininzi nesixabisekileyo kumxube owomileyo wodaka.Indibaniselwano yayo ekhethekileyo yeepropati, kubandakanywa nokugcinwa kwamanzi, amandla okuqina kunye nokubambelela okuphuculweyo, kuyenza ibe yinto ephambili kwizicelo ezahlukeneyo zokwakha.Njengoko ishishini lokwakha liqhubeka nokuvela, indima ye-HPMC ekuphuculeni ukusebenza kunye nokuzinza kodaka oluxubeneyo owomileyo kusenokwenzeka ukuba lunyuke, ngaloo ndlela lube negalelo kwiindlela zokwakha ezisebenzayo nezizinzileyo.
