Self-leveling compound yog cov khoom siv hauv pem teb uas siv los ua ib qho chaw tiaj tus thiab theem saum npoo ntawm cov vuas los yog lwm yam khoom siv hauv pem teb. Cov tshuaj no yog tsim los ntawm ntau yam ntaub ntawv, tab sis ib qho tseem ceeb tshaj plaws yog HPMC (hydroxypropyl methylcellulose). HPMC plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm tus kheej-leveling compounds thiab tseem ceeb heev rau kev txhim kho kev ua tiav ntawm flooring.
Ib qho txiaj ntsig tseem ceeb ntawm HPMC hauv kev sib txuas ntawm tus kheej yog nws lub peev xwm los txhim kho cov khoom ntws ntawm cov khoom. Thaum ntxiv rau qhov sib tov, HPMC ua raws li tus neeg sawv cev thickening, tiv thaiv cov khoom sib xyaw kom tsis txhob ua kua dhau lawm thiab tso cai rau nws kom sib npaug ntawm qhov chaw. Qhov no yog ib qho tseem ceeb kom ntseeg tau tias qhov kawg tshwm sim yog qhov du thiab qib nto, vim tias qhov tsis sib xws hauv qhov sib xyaw tuaj yeem ua rau muaj teeb meem thaum lub sijhawm teeb tsa. HPMC kuj tseem pab tiv thaiv kev tsim cov hnab tshos huab cua, uas tuaj yeem ua rau tsis muaj zog ntawm cov khoom siv hauv pem teb thiab cov substrate.
Lwm qhov txiaj ntsig tseem ceeb ntawm HPMC yog nws lub peev xwm los txhim kho cov khoom sib txuas ntawm tus kheej-leveling compounds. HPMC muaj cov pab pawg hydroxyl uas tuaj yeem cuam tshuam nrog lwm cov molecules, tso cai rau nws tsim cov ntawv cog lus muaj zog nrog cov substrates thiab cov ntaub ntawv hauv pem teb. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj cov av noo siab, qhov chaw sib txuas yuav raug dej los yog lwm yam kua. HPMC ua raws li kev thaiv, tiv thaiv dej los ntawm kev nkag mus rau saum npoo thiab ua rau puas tsuaj rau cov khoom siv hauv substrate lossis cov ntaub pua plag.
Ntxiv nrog rau nws cov khoom siv lub cev, HPMC yog cov khoom siv zoo ib puag ncig uas tuaj yeem siv tau zoo hauv qhov chaw sab hauv tsev. Tsis zoo li lwm yam tshuaj siv hauv kev tsim kho, HPMC tsis muaj tshuaj lom thiab tsis tso pa phem lossis cov pa phem. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov vaj tsev nyob thiab kev lag luam uas kev noj qab haus huv thiab kev nyab xeeb ntawm cov neeg nyob yog qhov tseem ceeb tshaj plaws.
Muaj ntau hom HPMC, txhua tus muaj peev xwm thiab cov yam ntxwv tshwj xeeb. Qee hom yog tsim los siv rau hauv cov ntaub ntawv hauv pem teb, thaum lwm tus yog siv rau hauv cov tshuaj, tshuaj pleev ib ce, thiab khoom noj khoom haus. Thaum xaiv HPMC rau kev siv cov khoom sib txuas ntawm tus kheej, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev cai tshwj xeeb ntawm qhov project thiab xaiv cov khoom uas sib xws nrog lwm cov ntaub ntawv siv.
Qhov tseem ceeb ntawm HPMC nyob rau hauv tus kheej-leveling compounds tsis tuaj yeem overstated. Cov khoom siv no yog qhov tseem ceeb rau kev tsim kom muaj qhov du, theem saum npoo haum rau kev txhim kho cov ntaub ntawv hauv pem teb. Txhim kho cov khoom ntws ntawm cov roj hmab, txhim kho nws cov khoom nplaum, thiab yog ib puag ncig zoo thiab muaj kev nyab xeeb siv. Cov neeg cog lus thiab cov neeg tsim khoom uas xav tsim kom muaj kev txhim kho zoo hauv pem teb yuav tsum xav txog kev siv HPMC nyob rau hauv tus kheej-leveling compound kom ua tiav cov txiaj ntsig zoo tshaj plaws.
