I-HPMC (i-Hydroxypropyl Methylcellulose) i-polymer eguquguqukayo, ephezulu yokusebenza esetyenziswa kakhulu kushishino lokwakha, ngokukodwa njengesongezo se-samente-based, i-gypsum-based kunye nezinye izinto zokwakha. Iphucula kakhulu umgangatho kunye nokuqina kwezinto zokwakha ngokuphucula ukugcinwa kwamanzi, ukusebenza kokwakhiwa kunye nokubambelela kwizinto eziphathekayo.
1. Ukugcinwa kwamanzi okugqwesileyo
Omnye weyona misebenzi iphambili ye-HPMC kukusebenza kwayo okugqwesileyo kokugcinwa kwamanzi, okunokuphucula kakhulu izinga lokugcinwa kwamanzi kwizinto ezifana nodaka kunye negypsum. Kwi-cement mortar, i-tile adhesive okanye izinto ezisekelwe kwi-gypsum, i-HPMC inciphisa ukulahlekelwa kwamanzi ngokwenza ifilimu encinci ukuqinisekisa ukuba izinto eziphathekayo zigcina umswakama ofanelekileyo ngexesha lokunyanga. Oku akugcini nje ukwandisa ixesha lokusebenza kwezinto eziphathekayo, kodwa kwakhona kuphucula umgangatho wokwakha kunye nokusebenza kakuhle. Ngokukodwa phantsi kweemeko ezigqithisileyo ezifana nobushushu obuphezulu kunye nokufuma okuphantsi, ukugcinwa kwamanzi okusebenzayo kwe-HPMC kubaluleke kakhulu.
Ukuphucula ukusebenza kokwakhiwa: Ngokugcina umswakama, i-HPMC yandisa ngokufanelekileyo ixesha elivulekileyo lezinto ezifana nodaka kunye ne-gypsum, ukwandisa ixesha lokusebenza kwabasebenzi, kwaye ngaloo ndlela iphucula ukuguquguquka kokwakhiwa.
Nciphisa ukuqhekeka: Ekubeni ubumanzi bezinto eziphathekayo buba ngumphunga ngokukhawuleza ngexesha lenkqubo yokomisa, ingxaki yokuqhekeka okubangelwa ukulahlekelwa kwamanzi amaninzi iyancitshiswa, ngokukodwa kwizicelo ezinqamlekileyo (ezifana ne-tile, yangaphakathi kunye nodonga lwangaphandle, njl.).
2. Ukuphucula ukusebenza kolwakhiwo
I-HPMC inesiphumo esihle kakhulu sokuqina, esenza ukuhambelana kwezinto ezifana nodaka kunye negypsum iyunifomu ngakumbi emva kokuxuba, ngokufanelekileyo ukuphepha isenzeko sokudilika kunye nokuwa kwezinto ngexesha lokwakha. I-viscosity yayo eyahlukeneyo kunye nobunzima bemolekyuli yenza ukuba i-HPMC iqhelane neemeko ezahlukeneyo zesicelo sokwakha, njenge:
Kwizinto zokubambelela kwi-tile, inokuphucula ukudibanisa kwezinto zokuqinisekisa ukuba iileyili zinokuqiniswa ngokuqinileyo kwiindonga okanye phantsi.
Kudaka eludongeni, i-HPMC inokwenza udaka lube lula ukulusebenzisa kwaye lugudise, kwaye luthintele udaka ekubeni lube lulwelo kakhulu kwaye luchaphazele ulwakhiwo.
HPMC kwakhona ukuthanjiswa elungileyo, nto leyo enokunciphisa ingxabano phakathi kwezixhobo kunye nezixhobo ngexesha lokwakha, ukwenza inkqubo yokwakha igudileyo. Oku kuthambisa akunciphisi kuphela ukuxhathisa kodaka, kodwa kukwaphucula ukusebenza kakuhle kunye nomgangatho wokusetyenziswa kodaka.
3. Ukuphuculwa kwamandla okudibanisa
Amandla okudityaniswa kwezixhobo zokwakha sisalathisi somsebenzi obalulekileyo, ngakumbi kwizinto ezifana nokuncamathelisa iithayile kunye nodaka lokufakelwa kwe-thermal. I-HPMC iqinisekisa ukuqina kwexesha elide lezinto zokwakha ngokuphucula ukunamathela phakathi kodaka okanye i-adhesive kunye ne-substrate. Lo msebenzi wokubambelela wokuqina ubalulekile ekubekweni kwezinto ezifana neethayile kunye neebhodi zegypsum, kwaye unokuthintela ngokufanelekileyo ukuba izinto zingawi okanye zijike ngenxa yokungaqhubi kakuhle.
I-HPMC, ngeziphumo zayo zokujiya kunye nokugcinwa kwamanzi, yenza i-samente hydration reaction yodaka iphelele ngakumbi ngexesha lenkqubo yokuqina emva kokwakhiwa, isenza isakhiwo esiqinileyo sokudibanisa. Ke ngoko, amandla okuqina, amandla oxinzelelo kunye nokuqina kwezinto emva kokumiswa kuphuculwe kakhulu.
4. Ukuphuculwa kokusebenza okuchasene nokutyibilika
Ngethuba lokubeka iileyile, ukusebenza kwe-anti-slip sisalathisi esibalulekileyo sokuvavanya umgangatho wezinto eziphathekayo. I-HPMC iphucula i-thixotropy yezinto zokuncamathelisa iithayile, iyenze kube lula ukuba iithayile zityibilike xa zibekwe kwindawo ethe nkqo. Olu phawu lubaluleke kakhulu ekubekeni iithayile ezinkulu, ukuqinisekisa ukuba iithayile zinokubekwa ngokuchanekileyo kwaye aziyi kutyibilika ngenxa yomxhuzulane, ngaloo ndlela kuphuculwe ukuchaneka kolwakhiwo kunye nobuhle.
Ukongeza, ukusebenza kwe-anti-slip ye-HPMC kunokunciphisa ukusebenza kwakhona ngokungeyomfuneko ngexesha lokwakha, ukuphucula ukusebenza kakuhle kolwakhiwo, kunye nokunciphisa inkunkuma yezinto eziphathekayo.
5. Ukomelezwa kokumelana nokunyibilika komkhenkce
Kwiindawo ezibandayo, izinto zokwakha zijongene nocelomngeni lwemijikelo yokunyibilika komkhenkce. Ukutshintsha okuphindaphindiweyo kweqondo lokushisa kuya kubangela ukwandiswa kunye nokunciphisa izinto eziphathekayo, ngaloo ndlela kuchaphazela ukuzinza nokuqina kwazo. Ukongezwa kwe-HPMC kunokuphucula ngokubonakalayo ukuxhathisa umkhenkce-kunyibilika kwezinto ezifana nodaka, kwaye kuthintele iintanda okanye ukuxobulwa kwemathiriyeli ngenxa yemijikelo yokunyibilika komkhenkce.
I-HPMC yenza ulwakhiwo lwe-membrane oluguquguqukayo kwizinto ezisekelwe kwisamente ngokusebenzisa isiphumo sokugcina amanzi, esinokuthi sithintele uxinzelelo olubangelwa kukutshintsha kobushushu kunye nokunciphisa umonakalo obangelwa kukwandiswa okanye ukucutheka kwezinto. Ngoko ke, isetyenziswa ngokubanzi kwizicelo zokwakha ezineemfuno eziphezulu zokumelana ne-freeze-thaw, njengeenkqubo zangaphandle zokugquma udonga kunye nezixhobo zomgangatho.
6. Ayinabungozi kokusingqongileyo kwaye ayinabungozi
I-HPMC yipolymer ephilayo ezinzileyo ngokwekhemikhali engakhuphi iigesi eziyingozi okanye izinto ezingcolisa umzimba, kwaye ihlangabezana neemfuno eziphezulu kushishino lolwakhiwo lwangoku lokhuseleko lokusingqongileyo kunye nempilo. Ngexesha lenkqubo yesicelo, i-HPMC ayiyi kuba nemiphumo emibi emzimbeni womntu, kwaye kulula ukuthotywa kwimeko yendalo, ehambelana nokusingqongileyo.
Olu phawu lungenabutyhefu kunye nokusingqongileyo lwenza ukuba i-HPMC ibe lolona khetho lufanelekileyo kwizinto zokwakha eziluhlaza, ngakumbi kwizinto ezifana neepeyinti kunye nomgubo weputty osetyenziswa ngokubanzi ekuhombiseni ngaphakathi. Inokunciphisa ngokufanelekileyo ungcoliseko lwangaphakathi kwaye iqinisekise ukhuseleko kunye nempilo yendawo yokuhlala.
7. Ukuphucula ukumelana neekhemikhali
Izinto zokwakha zihlala zifuna ukujongana nokukhukuliseka kweekhemikhali ezahlukeneyo ngexesha lokusetyenziswa, njengemvula ye-asidi, igesi yenkunkuma yamashishini, i-detergents, njl njl. I-HPMC inokuphucula kakhulu ukuxhatshazwa kweekhemikhali ze-corrosion kunye nokwandisa ubomi benkonzo yezinto. Ngokukodwa kwezinye izinto zokwakha ezivezwe kwimeko yangaphandle, i-HPMC inokubonelela ngomqobo wokukhusela okongeziweyo kwizinto eziphathekayo, ukunciphisa ukukhukuliseka kweekhemikhali kwizinto eziphathekayo, kunye nokugcina ukuzinza kokusebenza kwazo.
8. Ezinye iipropati
Ukongeza kwezi mpawu zingentla, i-HPMC inezinye iipropathi ezibalulekileyo kwizicelo zokwakha:
I-Anti-sagging: Isiphumo sokutyeba se-HPMC sinokugcina izinto ezifana nodaka kunye nepeyinti zizinzile emva kokufakwa kwesicelo, kwaye akukho lula ukugoba.
Ukuphucula ukusebenza kakuhle kolwakhiwo: Ekubeni i-HPMC inokuphucula ngokufanelekileyo ukusebenza kolwakhiwo lwemathiriyeli, inciphisa inkunkuma yezinto eziphathekayo kunye nokusebenza ngokutsha, ngaloo ndlela iphucula ukusebenza kakuhle kolwakhiwo ngokubanzi.
Ixesha elivulekileyo elongeziweyo: I-HPMC inokwandisa ixesha elivulekileyo lemathiriyeli, yandise ukuguquguquka kolwakhiwo, kwaye ivumele abasebenzi ukuba bahlengahlengise kwaye balungise iziphumo zokwakha ixesha elide.
Njengesongezo sezinto zokwakha eziphezulu, i-HPMC inokugcinwa kwamanzi okugqwesileyo, ukusebenza kolwakhiwo, amandla okubopha kunye nobuchule bokuchasana nokutyibilika, kwaye iqhuba kakuhle ekukhuselweni kwendalo, ukuxhathisa imichiza kunye nokumelana nokuqhaqhazela. Akunakuphucula kuphela umgangatho wezinto zokwakha, kodwa nokuphucula ukusebenza kakuhle kokwakhiwa kunye nokunciphisa inkunkuma yezinto. Ke ngoko, i-HPMC inoluhlu olubanzi lwezicelo ezilindelekileyo kushishino lokwakha, ngakumbi kwizinto ezisekwe kwisamente kunye negypsum, iHPMC iye yaba sisithako esibalulekileyo esiyimfuneko.
