Gypsum joint compound, inozivikanwawo sedrywall matope kana kungobatanidza musanganiswa, chinhu chekuvaka chinoshandiswa mukuvaka uye kugadzirisa kwe drywall.Iyo inonyanya kuumbwa ne gypsum powder, iyo yakapfava sulfate mineral inosanganiswa nemvura kuti igadzire paste.Iyi paste inozoiswa kune seams, makona, uye magedhi pakati pe drywall mapaneru kuti agadzire nzvimbo yakatsetseka, isina musono.
Hydroxypropyl methylcellulose (HPMC) is cellulose ether iyo inowanzowedzerwa kune plaster joint zvinhu nekuda kwezvikonzero zvakasiyana.HPMC inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro.Heano zvimwe zvakakosha zvekushandisa HPMC mune plaster joint compound:
Kuchengeta Mvura: HPMC inozivikanwa nekunaka kwayo kuchengetedza mvura.Kana yawedzerwa kune plaster joint compound, inobatsira kudzivirira musanganiswa kubva pakuoma nekukasira.Iyo yakawedzerwa nguva yekushanda inoita kuti zvive nyore kushandisa uye kupedzisa iyo yakabatana zvinhu.
Kuvandudzwa kwekugadzirisa: Kuwedzerwa kweHPMC kunosimudzira kufambiswa kweiyo yakabatana komboni.Inopa kugadzikana kwakatsetseka, zvichiita kuti zvive nyore kuisa uye kuisa kune drywall nzvimbo.Izvi zvakanyanya kukosha pakuwana mhedzisiro inotaridzika.
Adhesion: HPMC inobatsira musanganiswa unonamatira kune yakaoma wall pamusoro.Inobatsira musanganiswa kunamatira zvakasimba kune seams uye majoini, kuve nechokwadi chakasimba uye chinogara kwenguva refu chisungo kana chinhu chaoma.
Deredza shrinkage: Gypsum majoini zvinhu zvinowanzoita kupera kana zvaoma.Kuwedzerwa kweHPMC kunobatsira kuderedza shrinkage uye kuderedza mukana wekutsemuka kuoneka panzvimbo yakapera.Izvi zvakakosha kuti uwane mhedzisiro yakakwana uye inogara kwenguva refu.
Mhepo Inopinza Mumiririri: HPMC inoshandawo semhepo inopinza mumiriri.Izvi zvinoreva kuti inobatsira kubatanidza microscopic mabhubhu emhepo mune seam zvinhu, kuvandudza kuita kwayo kwese uye kusimba.
Consistency Control: HPMC inopa hukuru hukuru pamusoro pekuenderana kwemubatanidzwa wemubatanidzwa.Izvi zvinogonesa kuwana iyo inodiwa manyorerwo uye ukobvu panguva yekushandisa.
Izvo zvakakosha kuti uzive kuti iyo chaiyo magadzirirwo egypsum akabatanidzwa zvinhu anogona kusiyana kubva kumugadziri kuenda kune mugadziri, uye akasiyana mamakisi eHPMC anogona kushandiswa zvichienderana neinodiwa zvivakwa zvekupedzisira chigadzirwa.Pamusoro pezvo, zvimwe zvinowedzera zvakaita semakobvu, mabhainda uye zvidzoreso zvinogona kuverengerwa mukugadzira kuti uwedzere mashandiro.
Hydroxypropyl methylcellulose (HPMC) cellulose ether inoita basa rakakosha mukuvandudza kushanda, kunamatira uye kuita kwese kwegypsum joint compounds inoshandiswa mukuvaka nekugadzirisa drywall.Zvimiro zvaro zvakasiyana-siyana zvinobatsira kuwana kupera kwakatsetseka uye kwakasimba pane drywall nzvimbo.
