Cellulose, inozivikanwawo sehydroxypropylmethylcellulose (HPMC), chinhu chakakosha chegypsum. Gypsum chinhu chinoshandiswa zvakanyanya pamadziro nedenga rekuvaka. Chinopa nzvimbo yakatsetseka, yakaenzana yakagadzirira kupenda kana kushongedza. Cellulose chinhu chisina chepfu, chine hushamwari kune zvakatipoteredza uye chisina njodzi chinoshandiswa kugadzira gypsum.
Cellulose inoshandiswa mukugadzira gypsum kuvandudza hunhu hwegypsum. Inoshanda sechinamira, ichibata plaster pamwe chete uye ichidzivirira kuti isatsemuke kana kuderera painooma. Nekushandisa cellulose mumusanganiswa we stucco, unogona kuwedzera simba uye kugara kwenguva refu kwe stucco, zvichiita kuti igare kwenguva refu uye isingadi kugadziriswa zvakanyanya.
HPMC ipolymer yechisikigo inobva mu cellulose, ine cheni refu dzeglucose, inogadziriswa nekuita nepropylene oxide nemethyl chloride. Chinhu ichi chinoora uye hachina chepfu, chinhu chisina njodzi kunharaunda. Kunze kweizvozvo, HPMC inonyungudika mumvura, zvinoreva kuti inogona kusanganiswa nyore nyore mumusanganiswa wegypsum paunenge uchiigadzira.
Kuwedzera cellulose mumusanganiswa we stucco kunobatsirawo kuvandudza hunhu hwe stucco. Mamorekuru e cellulose ndiwo anokonzera kuumba chisungo pakati pe stucco nepasi pevhu. Izvi zvinoita kuti plaster inamire zviri nani pamusoro uye inodzivirira kuti isaparadzane kana kutsemuka.
Imwe mukana wekuwedzera cellulose mumusanganiswa wegypsum ndeyekuti inobatsira kuvandudza kushanda kwegypsum. Mamorekuru ecellulose anoshanda semafuta, zvichiita kuti zvive nyore kuti plaster ipararire. Izvi zvinoita kuti zvive nyore kuisa plaster pamadziro kana padenga, zvichiita kuti pamusoro payo pave panyoro.
Cellulose inogonawo kuvandudza chitarisiko chepurasita. Nekuwedzera simba uye kushanda kwestucco, inobatsira kuona kuti purasita yakatsetseka, yakaenzana isina maburi kana kusakwana pamusoro. Izvi zvinoita kuti purasita iwedzere kutaridzika zvakanaka uye ive nyore kupenda kana kushongedza.
Kuwedzera kune zvakanakira zvataurwa pamusoro apa, cellulose inobatsirawo mukudzivirira moto kwestucco. Kana ikaiswa mumusanganiswa wegypsum, inogona kubatsira kuderedza kupararira kwemoto nekugadzira chipingamupinyi pakati pemoto nemadziro kana pamusoro pedenga.
Kushandisa cellulose mukugadzira gypsum kunewo mabhenefiti akati wandei ezvakatipoteredza. Chinhu ichi chinoora uye hachina chepfu, hachikuvadzi nharaunda nehutano hwevanhu. Pamusoro pezvo, sezvo cellulose ichiwedzera simba uye kugara kwenguva refu kweplaster, inobatsira kuderedza huwandu hwekugadzirisa hunodiwa nekufamba kwenguva. Izvi zvinoderedza huwandu hwemarara anogadzirwa uye zvinobatsira kuchengetedza zviwanikwa.
Cellulose chinhu chakakosha chegypsum. Kuiisa mumusanganiswa westucco kunobatsira kuvandudza kusimba, kugara kwenguva refu, kushanda zvakanaka uye chitarisiko chestucco. Uye zvakare, ine mabhenefiti akawanda ezvakatipoteredza anobatsira kuderedza kudiwa kwekuchengetedza kwenguva refu. Kushandisa cellulose mugypsum idanho rakakosha pakugadzira zvinhu zvekuvaka zvinogara kwenguva refu uye zvine hushamwari kune zvakatipoteredza.
