Udaka lodaka olugqumayo lwe-HPMC thermal

Udaka lokwambathisa ubushushu lwe-HPMC lubhekisa kwizinto zokwakha ezilungisiweyo aphoi-hydroxypropyl methylcellulose (HPMC)yongezwa njengesithako kwi-thermal insulation mortar. I-HPMC yi-non-ionic cellulose ether enokugcinwa kakuhle kwamanzi, ukutyeba, ukusebenza kakuhle kolwakhiwo kunye neempawu zokubopha. Isetyenziswe kakhulu ekwakheni i-mortar, i-putty powder, i-tile adhesive, i-thermal insulation mortar kunye neminye imimandla.

1. Indima ye-HPMC kwi-thermal insulation mortar

Injongo ephambili yokongeza i-HPMC kwi-thermal insulation mortar kukuphucula ukusebenza kwayo, ukugcinwa kwamanzi, ukubopha kunye neempawu zokungatyibiliki, ukuqinisekisa ulwakhiwo lwayo olulula, kunye neempawu ezilungileyo zoomatshini kunye nokuqina emva kokuqina. Imisebenzi ethile yile ilandelayo:

1.1. Ukugcinwa kwamanzi okunamandla

I-HPMC inokuphucula kakhulu ukugcinwa kwamanzi kwi-mortar, ithintele ukulahleka kwamanzi ngokukhawuleza ngexesha lokwakhiwa, iqinisekise ukufuma kwesamente ngokwaneleyo, ngaloo ndlela iphucule amandla okubopha kunye namandla ngokubanzi kwi-mortar.

1.2. Ukuphucula ukusebenza kolwakhiwo

Ngenxa yokuthambisa okuhle kunye nefuthe lokutyeba le-HPMC, i-mortar ithambile ngakumbi, igudile, kulula ukuyisebenzisa nokuyila, inciphisa ukutshiza kunye nokuwa kothuthu, kwaye iphucula ukusebenza kakuhle kolwakhiwo.

1.3. Ukunamathela okwandisiweyo

I-HPMC inokuphucula ukunamathelana phakathi kwesamente kunye nomaleko osisiseko, iphephe ukuchitheka nokugrumba, kwaye iphucule uzinzo lomaleko wokwambathisa ubushushu ngokubanzi.

1.4. Thintela ukugoba

Ngexesha lokwakhiwa kodonga oluthe nkqo, i-HPMC inokuphucula ukusebenza kwe-mortar engagungqiyo, ukuze ihlale izinzile ngexesha lokwakhiwa kwe-coating etyebileyo kwaye kungabi lula ukuyityibiliza.

2. Iimpawu zokusebenza kwe-HPMC insulation mortar

Ilula kwaye inamandla aphezulu: Izinto ezikhaphukhaphu ezingaphiliyo ezifana ne-perlite ekhulisiweyo kunye neglasi ye-foam zihlala zongezwa kwi-mortar. Xa zisetyenziswa ne-HPMC, kungaveliswa umaleko wokugquma okhaphukhaphu nonamandla aphezulu.

Ukuqhuba kobushushu obuphantsi: Ukuqhuba kobushushu ngokubanzi kuphakathi kwe-0.045 kunye ne-0.065 W/m·K, nto leyo ethintela ngempumelelo ukuqhubela kobushushu kwaye iphucule ukusebenza kakuhle kwamandla kwezakhiwo.

Ukumelana nemozulu okuhle: Phantsi kwesenzo se-HPMC, ukuqina kunye nokumelana nokuqhekeka kwe-thermal insulation mortar kuyaphuculwa, kwaye inokukwazi ukuziqhelanisa notshintsho lwemozulu olwahlukeneyo.

Ukhuseleko lwendalo kunye nokungabi natyhefu: I-HPMC sisixhobo esiluhlaza nesinobuhlobo nokusingqongileyo, esihambelana nezinto ezingaphiliyo ezifana nesamente nesanti, kwaye asikhuphi izinto eziyingozi.

3. Intsimi yesicelo

I-HPMC thermal insulation mortar isetyenziswa kakhulu kwicandelo lenkqubo yokukhusela udonga lwangaphandle, ukhuseleko lodonga lwangaphakathi, ukhuseleko lophahla, njl.njl. kwizakhiwo ezahlukeneyo. Ifanelekile ngokukodwa kwiiprojekthi zokuhlaziya ezonga umbane, izakhiwo ezikwiindawo ezibandayo, izakhiwo zikawonke-wonke, njl.njl., nto leyo enefuthe elikhulu ekongeni umbane kwezakhiwo nasekuthuthuzeleni.

4. Amanyathelo okulungisa ulwakhiwo

Umlinganiselo ofanelekileyo: Udaka lokufakelwa kobushushu lwe-HPMC kufuneka lulungiswe ngokuchanekileyo ngokweemfuno zoyilo kunye neemeko zokwakha, kwaye ubungakanani be-HPMC kufuneka bulawulwe ngokubanzi phakathi kwe-0.2% kunye ne-0.5% (ngobunzima bomgubo owomileyo).

Xuba ngokulinganayo: Xa uxuba, izinto ezomileyo mazixutywe ngokulinganayo kuqala, emva koko kongezwe amanzi aze axutywe ngokulinganayo, aze axutywe kwakhona emva kokuma imizuzu embalwa.

Ulawulo lwemeko yokwakha: Kuphephe ukwakha kwindawo enobushushu obuphezulu okanye enomoya ukuze uthintele ukufuma kwesamente ukuba kungatshi ngokukhawuleza kwaye kuchaphazele isiphumo.

Unyango lwesiseko: Isiseko masicoceke, singabi naoyile kwaye singabi nathuli, kwaye simanziswe xa kuyimfuneko ukuqinisekisa ukuba sinamathelana kakuhle.

Ulawulo lobukhulu bolwakhiwo: Ubukhulu bokuplasta ngakunye akufuneki bube bukhulu kakhulu, ngokubanzi bulawulwe ngaphakathi kwe-1.5cm, kwaye ulwakhiwo lobukhulu bomaleko kufuneka lwenziwe ngamaqoqo ukuthintela ukuqhekeka nokuqhekeka.

Udaka lokwambathisa ubushushu lwe-HPMC, njengesixhobo sokwakha esonga amandla esisebenza kakuhle, sidibanisa ubushushu, ubushushu, ulwakhiwo olulula, ukhuseleko olusebenzayo kunye nokusingqongileyo, kwaye sisetyenziswa kakhulu kwizakhiwo eziluhlaza zanamhlanje. Ukongezwa kwe-HPMC akuphuculi nje kuphela ukusebenza ngokupheleleyo kodaka, kodwa kuqinisekisa ngokufanelekileyo umgangatho wokwakha kunye nokuqina kobunjineli. Yindlela ebalulekileyo yobugcisa yokukhuthaza ukugcinwa kwamandla esakhiwo kunye nokwakhiwa okusemgangathweni ophezulu. Kwixesha elizayo, ngophuhliso olukhawulezayo lwezakhiwo eziluhlaza, udaka lobushushu lwe-HPMC luya kudlala indima ebaluleke ngakumbi kwinkqubo yokonga amandla yesakhiwo.
