.Nalysis ya zoyambitsa zoyambitsa za gypsim sypsum
1. Kusanthula kwa Chuma cha Gyptum Raw
a) Malo omanga osavomerezeka
Gypsum gypsum imakhala ndi kuchuluka kwa matenda a dihydrate gypsum, yomwe imatsogolera kuphunzitsidwa mwachangu kwa gypsim. Pofuna kupanga gypsum gypsum kukhala ndi nthawi yotseguka, yokhotakhotanso kuyenera kuwonjezeredwa kuti zinthu zisinthe; Solduby anhydrous gypsum mu gypsum aiii mulingo wambiri, aiii akukula kwambiri kuposa β-hemihydrate mu gawo lachilendo, ndipo kusintha kwa kuchuluka kwa gypsim ndi kosasinthika pakachiritso; Zomwe zili ndi gypsihydrate gypsum mu gypsum yotsika, ndipo ngakhale kuchuluka kwa calcium sulfate yotsika; Tizilombo tating'onoting'ono tomwe timapanga gypsum siikwati ndipo palibe gradation.
b) zowonjezera zowonjezera
Sizili mkati mwa ma ph mitundu yogwira kwambiri ya obwezeretsa; Kusintha kwa gel osakhalitsa, kuchuluka kwa ntchito ndi kwakukulu, mphamvu ya gypsim yopaka imachepetsedwa kwambiri, nthawi yotsiriza inali yayitali; Kusunga kwamadzi kwa cellulose ether kuli otsika, kuwonongeka kwa madzi kumasala; cellulose ether imasungunuka pang'onopang'ono, osayenera kupanga makina opanga makina.
Yankho:
a) Sankhani gypsum yokhazikika komanso yokhazikika, nthawi yoyamba yokhala ndi 3min, ndipo mphamvu yotheratu ndi yoposa 3mm.
b) Sankhani cellulose ether yokhala ndi ting'onoting'ono ndi tinthu tating'onoting'ono toyambitsa matenda.
c) Sankhani wobwezeretsa yemwe alibe mphamvu pakukhazikitsa gypsim gypsim.
2. Kusanthula kwa omanga
a) Wogwiritsa ntchito makina ogwiritsa ntchito popanda zomangamanga ndipo sachita maphunziro apadera. Ogwira ntchito yomanga sanadziwe zoyambirira ndi zofunika pa gypsing gypsum, ndipo sangathe kugwira ntchito molingana ndi malamulo omanga.
b) Kuwongolera kwaukadaulo ndi kasamalidwe ka muuni wopangira ulengiring ndi ofooka, palibe ogwira ntchito pamalo omanga, ndipo ntchito zomwe sizigwirizana ndi ogwira ntchito sizingakonzedwe nthawi;
c) ambiri omwe alipo ndi gypsum omwe alipo ndi mawonekedwe a ntchito yoyeretsa, kuyang'ana kuchuluka komanso kunyalanyaza mtundu.
Yankho:
a) Kupatsiranitsa ma projekiti opangira ma projekiti kumalimbitsa pakuphunzitsidwa kwa ntchito ndikupangitsa kuwulula kwaukadaulo musanamangidwe.
b) kulimbikitsa kasamalidwe ka malo omanga.
3. Kusanthula kwa Pulating Plaster
a) Mphamvu yomaliza yopaka gypsum imakhala yotsika ndipo siyingathe kuthana ndi mavuto obwera chifukwa cha kutayika kwa madzi; Mphamvu yotsika ya gypsum imachitika chifukwa cha zida zopanda pake kapena njira zosafunikira.
b) kukana kwa gypsim yopaka gypsium sikuwoneka bwino, ndipo gypsim wopaka ma grester amadziunjikira pansi, ndipo makulidwe ndi akulu, akuyambitsa ming'alu.
c) Nthawi yosakanikirana ya gypsim matope ndi yayifupi, zomwe zimapangitsa kusakanikirana kwa matope, kutsika kwamphamvu, shrinka ndi kufalikira kwa gypsim wosanjikiza gypsim
d) Matope a gypsim omwe akhazikitsidwa kale angagwiritsidwe ntchito pambuyo powonjezera madzi.
Yankho:
a) Gwiritsani ntchito gypsum yoyenerera, yomwe imakwaniritsa zofunikira za GB / T2862720.
b) Gwiritsani ntchito zida zosakaniza kuti muwonetsetse kuti ndi gypsum ndi madzi ophatikizidwa.
c) Kuletsedwa kuwonjezera madzi kwa matope omwe adakhazikitsidwa, kenako gwiritsani ntchito
4. Chotsani kusanthula kwa maziko
a) Pakadali pano, zida zatsopano za khoma zimagwiritsidwa ntchito ngati ngodya za nyumba zotsogola, ndipo zowoneka bwino za shraders ndizokulirapo. Pamene m'badwo wa midadadawo siokwanira, kapena chinyezi cha mabatani ndi okwera kwambiri, etc. 3
b) Mgwirizano pakati pa chiwalo cha Connemete ndi makoma ndi pomwe zida ziwiri zosiyana zimakumana, ndipo mayanjano awo owonjezera ndi osiyana. Kutentha kwa kutentha, kuphatikizika kwa zinthu ziwirizi sikukukhumudwitsidwa, ndipo ming'alu yolekanitsidwa ikuwoneka. Makoma wamba okhoma ming'alu pakati pa mtengo ndi ming'alu yopingasa pansi pa mtengo.
c) Gwiritsani ntchito ma aluminium forwork kutsanulira konkriti patsamba. Pamwamba pa konkriti ndi yosalala ndipo imalumikizidwa bwino kwambiri pa pulasitiki yosanjikiza. Wopanda pulasitiki wosanjikiza amatulutsidwa mosavuta kuchokera pansi osanjikiza, zomwe zimapangitsa ming'alu.
d) Zowonjezera zapansi ndi gypsim zopaka gypseum zimakhala ndi kusiyana kwakukulu mu kalasi, ndipo pansi pa kutentha kwa shring shrinkage komanso mphamvu yotsika kwambiri, makamaka pamene gypsim wosanjikiza nthawi zambiri amatulutsa ayezi. Tambasulani kusokoneza, ngakhale malo akulu ogona. e) Malo osanjikiza ali ndi mayamwidwe amadzi ambiri komanso madzi othamanga mwachangu.
Yankho:
a) Kutsikira konkire yatsopano kuyenera kukhala kouma kwa masiku 10 m'chilimwe komanso masiku opitilira 20 nyengo yozizira pansi pa mpweya wabwino. Pamwamba pali yosalala ndipo maziko amatenga madzi mwachangu. Mthandizi ayenera kugwiritsidwa ntchito;
b) zolimbitsa zinthu monga nsalu za Grid zimagwiritsidwa ntchito pamsonkhano wa makoma a zinthu zosiyanasiyana
c) Zipangizo zopepuka za khoma ziyenera kusungidwa bwino.
5. Chifukwa Cholinga Chomanga
a) maziko osanjikiza ndi owuma popanda kunyowa kapena kugwiritsa ntchito wothandizira. Gypsim yojambula ikukhudzana ndi malo osanjikiza, chinyontho mu gypsim gypsim chimatayamwa, madziwo amatayika, ndipo kuchuluka kwa gypsim wosanjikiza, kumapangitsa ming'alu yamphamvu, ndikuchepetsa mphamvu yamphamvu.
b) Kumanga kwa maziko ndi osauka, ndipo ma gypsim omwe ali ndi gypsim omwe ali ndi vuto lalikulu. Ngati pulasitala yopatayo imayikidwa nthawi imodzi, matope adzagwa ndikupanga ming'alu yopingasa.
c) Kudophuka kwa hydroelect sikunagwiritsidwe ntchito bwino. Makina owala sadzazidwa ndi gypsum gypsum kapena konkriti wabwino wowonjezera, zomwe zimapangitsa kuphwanya, komwe kumayambitsa kuwonongeka kwa gypsim wosanjikiza.
d) Palibe chithandizo chapadera cha nthiti zopukutira, ndipo chiwonetsero cha gypsim chopangidwa ndi gypsim chomwe chimapangidwa m'malo akuluakulu a nthiti.
Yankho:
a) Gwiritsani ntchito mankhwala apamwamba kwambiri kuti mugwire maziko osanjikiza ndi mphamvu yotsika komanso madzi othamanga.
b) Kukula kwa gypsimbu wopaka gypsimbu ndikokulirapo, kupitirira 50mm, ndipo ziyenera kulumikizidwa.
c) ikani njira yomangayi ndikulimbitsa kasamalidwe ka malo omanga.
6. Chotsani Kusanthula Kwa Malo Omanga
a) Nyengo ndi youma komanso yotentha.
b) kuthamanga kwa mphepo
c) Pa nthawi yopuma ndi chilimwe, kutentha kumakhala kokwera komanso chinyezi ndi chotsika.
Yankho:
a) Ntchito yomanga siyiloledwa pomwe pali chimphepo champhamvu cha 5 kapena pamwambapa, ndi zomanga siziloledwa pomwe kutentha kwa kutentha ndikokwera kuposa 40 ℃.
b) Pa nthawi yanyengo ndi chilimwe, sinthani njira yopangira gypsum.
