Inzira ya gypsumu

Guhomesha plaster bizaba inzira nyamukuru yo guteramo urukuta rw'imbere mugihe kizaza

Gypsumu yo guhomesha ikoreshwa kurukuta rwimbere ifite ibiranga uburemere bworoshye, kwinjiza amazi, kubika amajwi, no kubaho neza. Ibikoresho byo guhomesha Gypsum bizahinduka inzira nyamukuru yo guteramo urukuta rwimbere mugihe kizaza.

Gypsum ya hemihydrate ikoreshwa muguhomesha urukuta rw'imbere muri iki gihe muri rusange ni β-hemihydrate gypsum, na hemihydrate desulfurized gypsum, cyangwa gypsum naturel, cyangwa fosifogi yujuje ibyangombwa byo kurengera ibidukikije ikoreshwa cyane. Imbaraga z'umubiri wa gypsumu ziratandukanye kuva 2.5 MPa kugeza MPa 10. Ubwiza bwa gypsumu ya hemihydrate yakozwe nabakora gypsumu iratandukanye cyane kubera itandukaniro ryinkomoko yibikoresho nibikorwa.

Igishushanyo mbonera cya Plastering Gypsum for Engineering

Gypsum yo guhomesha ikoreshwa mubuhanga mubusanzwe iremereye kandi yumusenyi wohomesha. Bitewe nubunini bunini bwubatswe, ubunini buringaniye burenga cm 1. Abakozi bakeneye kuringaniza byihuse, gypsum rero irasabwa kugira thixotropy nziza. Gusiba neza, kumva amaboko yoroheje, byoroshye guhura numucyo nibindi.

gusesengura:

1. Imikorere myiza yo kuringaniza. Itondekanya ry'umucanga nibyiza, koresha umucanga wo hagati n'umucanga mwiza.

2. Thixotropy nziza. Birasabwa ko ibintu byuzuza ibikoresho ari byiza. Urashobora kubona umubyimba, nanone ushobora kubona inanutse.

3. Nta gutakaza imbaraga. Koresha aside amine acide, nka Plast Retard yo mubutaliyani PE.

Igitekerezo cyatanzwe cyo gukora gypsum yubuhanga:

β-hemihydrate gypsumu yanduye: kg 250 (imbaraga za gypsumu ni MPa 3)

150-200 mesh calcium iremereye: kg 100 (calcium iremereye ntabwo byoroshye kuba byiza cyane)

1.18-0.6mm umucanga: 400 kg (mesh-30 mesh)

0,6-0.075mm umucanga: kg 250 (mesh 30 mesh-200)

HPMC-40.000: 1.5 kg (Birasabwa koza HPMC inshuro eshatu, ibicuruzwa byiza, gypsumu nkeya irabya, ubukonje buke, kumva neza ukuboko, hamwe nubunini buke butera umwuka).

Umukozi wa Rheologiya YQ-191/192: 0.5 kg (anti-sag, kongera kuzura, kumva amaboko yoroheje, kurangiza neza).

Plast Retard PE: 0.1 kg (dosage ntabwo ikosowe, ihinduwe ukurikije igihe coagulation, proteine, nta gutakaza imbaraga).

Urugero rwibikoresho:

Umucanga wa mm 1,18-0,6

0.6-0.075mm umucanga

β hemihydrate desifurize gypsum (hafi mesh 200)

Ibiranga iyi formula ni: kubaka neza, imbaraga zihuse. Biroroshye kurwego, ugereranije igiciro gito, ituze ryiza, ntabwo byoroshye gucamo. Bikwiranye nubuhanga.

Kuvuga uhereye kuburambe

1. Bitabaye ibyo, igihe cyo gushiraho ni kirekire cyane kandi biroroshye gucamo. Niba igihe ari gito cyane, igihe cyo kubaka ntabwo gihagije. Mubisanzwe, intangiriro yo gushiraho igihe cyo gushushanya ni iminota 60, kandi igihe cyanyuma cyo gushiraho gypsumu ni hafi yigihe cyo gutangira.

2. Ibyondo byumucanga ntibigomba kuba binini cyane, kandi ibyondo bigomba kugenzurwa kuri 3%. Ibyondo byinshi cyane biroroshye gucamo.

3. HPMC, ubukonje buke, ubuziranenge burasabwa. HPMC yogejwe inshuro eshatu zifite umunyu muke, kandi gypsum mortar ifite ubukonje buke. Ubu buso bukomeye nimbaraga ni byiza

4. Iyo kuvanga ifu yumye, igihe cyo kuvanga ntigikwiye kuba kirekire. Ibigize byose bimaze kugaburirwa, koga muminota 2. Ifu yumye, igihe kinini cyo kuvanga, nibyiza. Nyuma yigihe kinini, retarder nayo izimira. Ni ikibazo cyuburambe.

5. Kugenzura ibicuruzwa. Birasabwa kwigana no kugenzura ibicuruzwa byarangiye kuva intangiriro, hagati na nyuma ya buri nkono. Muri ubu buryo, uzasanga igihe cyo gushiraho gitandukanye, kandi retarder igomba guhindurwa uko bikwiye ukurikije ibikenewe.
