Te whakamatautau whakamatautau mo te hydroxypropyl methylcellulose:
1. Whakamātautau kaha: I muri i te whakamatautau, he pai te kaha o te hononga tensile me te kaha compressive hydroxypropyl methylcellulose gypsum-based.
2. Te whakamatautau anti-sagging: Karekau he sag i te wa e whakamahia ana te hangahanga kotahi-paahi i roto i nga paparanga matotoru, kaore hoki he sag ina tono mo te neke atu i te rua nga paahi (i runga ake i te 3cm), he pai te kirihou.
3. Te whakamatautau i runga i te pakitara: he maama me te maeneene i te wa e iri ana, ka taea te hanga i te wa kotahi.He ngawari, he ngawari te mata, me te kanapa.
4. Whakamātautau reeti horapa: Ko te tere horahanga o te turanga gypsum e pa ana ki te hua ka puta mai i te ine i te kiato tino makuku o te turanga gypsum.Kotahi tone o te hua gypsum mo te hanga i tetahi waahi pakitara 10mm te matotoru.
5. Te whakamatautau tere o te wai: te reiti pupuri wai paerewa tohutoro GB / T28627-2012 "Plastering Gypsum", ko te reiti pupuri wai o te raima raima raro marama he nui ake i te rite ranei ki te 60%, me te 0.2% me te 0.25% o te gypsum. ka taapirihia te hydroxypropyl methylcellulose He pai te mahi pupuri wai.
Ko nga ahuatanga ohydroxypropyl methylcellulose i roto i te kumete gypsum:
1. He pai te mahi hanga: he ngawari me te maeneene ki te whakairi, ka taea te hanga i te wa kotahi, me te kirihou i te wa ano.
2. Hototahi kaha: He pai mo nga momo turanga gypsum katoa, a ka taea te whakaiti i te wa totohu o te gypsum, te whakaiti i te tere o te whakamaroketanga o te whakamaroke, a kaore i te ngawari te pakaru o te pakitara me te pakaru.
3. He pai te pupuri i te wai: ka taea te whakaroa i te wa mahi o te turanga gypsum, te whakapai ake i te kaha o te pakari o te turanga gypsum, te whakanui ake i te kaha o te hononga i waenga i te turanga gypsum me te paparanga turanga, te pai o te mahi honohono maku, me te whakaiti i te pungarehu taunga me etahi atu raruraru.
4. Whakapai ake i te tere o te horahanga o te turanga gypsum: Ka whakatauritea ki te ether hydroxypropyl methylcellulose rite, ka tino piki ake te tere o te horahanga.Ka taea e nga hua Hydroxypropyl methylcellulose te whakanui ake i te reeti paninga, ka taea te kapi i nga waahi maha, ka taea te whakaiti i te kaha o te mahi, te penapena rauemi, me te whakapai ake i nga painga ohaoha.
5. He pai te mahi anti-sagging: i te wa e whakairihia ana nga paparanga matotoru, karekau te hanga kotahi-paahitanga, ka neke atu i te rua nga paahitanga, i runga ake i te 3cm, e kore e pakaru i te wa e iri ana, a he pai te kirihou.
6. Nga mara tono me te inenga: Maama te raima raima o raro, ko te inenga e taunakitia ana ko te 2.5-3.5 kg/ton.
