Ngwa nke Hydroxypropyl Methyl Cellulose na Gypsum Mortar

(1), njirimara nkehydroxypropyl methylcellulose na gypsum ngwa agha:

1. Ọmarịcha ihe owuwu dị mma: ọ dị mfe ma dị nro ka kpọgidere ya, enwere ike ịkpụzi ya n'otu oge, ma nwee plasticity n'otu oge.

2. Nkwekọrịta siri ike: Ọ dị mma maka ụdị gypsum dị iche iche, ma nwee ike ibelata oge nkwụsị nke gypsum, belata nkwụsị nke ihicha, na mgbidi adịghị mfe oghere na ịgbawa.

3. Ogologo njigide mmiri dị mma: ọ nwere ike ịgbatị oge ọrụ nke gypsum base, melite nkwụsi ike nke gypsum base, mee ka ike nke njikọ dị n'etiti gypsum base na base Layer, ezigbo ọrụ njikọ mmiri, ma belata ọdịda ọdịda na nsogbu ndị ọzọ.

4. Meziwanye mgbasa ozi nke gypsum base: E jiri ya tụnyere hydroxypropyl methylcellulose ether yiri ya, ọnụego mgbasawanye ga-abawanye nke ukwuu. Ngwaahịa Hydroxypropyl methylcellulose nwere ike ịbawanye ọnụego mkpuchi nke ukwuu, nwere ike kpuchie ọtụtụ ebe, nwere ike ibelata ike ọrụ, chekwaa ihe, ma melite uru akụ na ụba.

5. Ọmarịcha ihe mgbochi na-eme ka ọ dị mma: mgbe a na-ekokwasị akwa akwa, otu ihe na-arụ ọrụ na-agafe agaghị agafe, na ihe karịrị ụzọ abụọ, n'elu 3cm, agaghị eme ka ọ dị mma mgbe ọ na-ekokwasị, na plasticity dị mma.

6. Ngwa ngwa na usoro onunu ogwu: ìhè ala plasta gypsum, usoro a na-atụ aro bụ 2.5-3.5 kg / ton.

(2) Nnwale nnwale ngwa nke hydroxypropyl methylcellulose:

1. Nnwale ike: Mgbe ulechara, gypsum dabeere na hydroxypropyl methylcellulose nwere ezigbo ike njikọ ike na ike mkpakọ.

2. Nnwale mgbochi-sagging: Enweghị sag mgbe a na-etinye ihe owuwu otu ngafe na akwa akwa, na enweghị sag mgbe etinyere ihe karịrị ngafe abụọ (n'elu 3cm), na plasticity dị mma.

3. Nnwale nkwudo mgbidi: ọ na-adị ọkụ ma dị nro mgbe ọ na-ekowe, enwere ike ịkpụzi ya n'otu oge. N'elu dị nro ma dị nro, nwere nchapụta.

4. Nnwale mgbasa ozi: Ọnụ ọgụgụ na-agbasa nke gypsum base na-ezo aka na nsonaazụ enwetara site na ịlele njupụta mmiri mmiri nke gypsum base. Otu ton nke ngwaahịa gypsum maka iwu mgbidi 10mm gbara ọkpụrụkpụ.

5. Nnwale nlegharị anya mmiri: Ntụgharị mmiri na-ejigide ọkọlọtọ GB/T28627-2012 "Plastering Gypsum", ọnụ ọgụgụ njide mmiri nke ìhè ala plasta gypsum dị ukwuu karịa ma ọ bụ nhata 60%, na 0.2% na 0.25% nke gypsum dabeere na gypsum. A na-agbakwunye hydroxypropyl methylcellulose Ọ nwere ọrụ njigide mmiri dị mma.
