Ukusetyenziswa kunye nendima ye-cellulose ether kwizixhobo zokwakha ezahlukeneyo

I-Cellulose ether luhlobo lwe-polymer engeyiyo i-ionic semi-synthetic ene-water-soluble kunye ne-solvent-soluble, ebangela iindima ezahlukeneyo kumashishini ahlukeneyo, umzekelo, kwizixhobo zokwakha iikhemikhali, ineendima ezilandelayo ezidityanisiweyo:

① iarhente yokugcina amanzi ② isithambisi ③ ukulinganisa ④ ukwakha ifilimu ⑤ isibopheleli

Kwishishini le-PVC, yi-emulsifier, i-dispersant; kwishishini leyeza, yi-binder kunye ne-skeleton release materials ecothayo nelawulwayo, njl. Kungenxa yokuba i-cellulose ineendima ezahlukeneyo ezidibeneyo okwenza ukuba ibe noluhlu olubanzi lwezicelo. Oku kulandelayo kugxile ekusetyenzisweni nakwindima ye-cellulose ether kwizixhobo ezahlukeneyo zokwakha.

(1) Kwi-putty eludongeni:

Okwangoku, ilizwe lethu kwizixeko ezininzi, i-putty engangeni manzi, engangeni manzi, engangeni manzi, ixatyiswa kakhulu ngabantu kwiminyaka embalwa yokuqala, ngenxa yokusetyenziswa kweglue yokwakha eyenziwe nge-putty ekhupha umonakalo kwimpilo yabantu, iglue yokwakha yenziwe nge-polyvinyl alcohol kunye ne-formaldehyde acetal reaction. Ngoko ke le nto isuswa kancinci ngabantu, kwaye ithathe indawo yale nto yimveliso yochungechunge lwe-cellulose ether, oko kukuthi, uphuhliso lwezixhobo zokwakha ezinobuhlobo nokusingqongileyo, i-cellulose okwangoku yeyona nto inye kuphela.

Kwi-putty engangeni manzi yahlulwe yaba yi-putty kunye ne-putty paste, iintlobo ezimbini ze-putty zikhethwa ngokubanzi yi-methyl cellulose eguquliweyo kunye ne-hydroxypropyl methyl. Iintlobo ezimbini ze-putty zikhethwa ngokubanzi kwi-30000-60000cps phakathi kweyona ifanelekileyo, indima ephambili ye-putty cellulose kukugcina amanzi, ukubopha, ukuthambisa kunye nezinye iindima. Ngenxa yokuba abavelisi abahlukeneyo be-putty bafana, ezinye ziyi-calcium engwevu, i-calcium ekhanyayo, isamente emhlophe, njl., ezinye ziyi-powder ye-gypsum, i-calcium engwevu, i-calcium ekhanyayo, njl., ngoko ke iifomyula ezimbini zikhethwa ngokweenkcukacha ze-cellulose viscosity kwaye ukungena kwayo kuyafana, ubungakanani be-accession ngokubanzi yi-2 ‰ -3 ‰ okanye ngaphezulu. Ekukhuhleni ulwakhiwo lwe-wall putty, ngenxa ye-substrate yodonga, kukho inqanaba elithile lokufunxwa kwamanzi (izinga lokufunxwa kwamanzi eludongeni lwezitena yi-13%, i-concrete yi-3-5%), edibene nehlabathi langaphandle lokufuma, ngoko ke ukuba i-putty ilahlekelwa ngamanzi ngokukhawuleza, iya kukhokelela kwiintanda okanye ekususweni komgubo kunye nezinye izinto, ngaloo ndlela ibuthathaka amandla e-putty, ngenxa yesi sizathu, emva kokongeza i-cellulose ether kuya kuyisombulula le ngxaki. Kodwa umgangatho we-filler, ingakumbi umgangatho we-gray calcium nawo ubaluleke kakhulu.

Kuba I-cellulose ine-viscosity ephezulu, ngaloo ndlela kukwaphucula ukunamathela kwe-putty, kodwa kwakhona kuthintele ukwakhiwa kwento yokuxhoma, kwaye kukhuhlwe emva kokuba kukhululekile ngakumbi, konga abasebenzi njl.njl. Kwi-powder eyomileyo, i-putty cellulose ether kufuneka ifaneleke ukongeza amanqaku angaphezulu, imveliso yayo, ukusetyenziswa kwayo kulula ngakumbi, i-filler kunye nezongezo zomgubo owomileyo umxube ofanayo unokuba lula ngakumbi, ukwakhiwa kukwalula ngakumbi, amanzi kwindawo, kunye nokuba kungakanani kunye nokuba kungakanani.

(2) udaka lwesamente:

Kwisigqubuthelo sekhonkrithi, ngokwenene sifikelele kumandla okugqibela, kufuneka senze isamente iphendule ngokupheleleyo ngamanzi kuphela, ingakumbi ehlotyeni, ukulahleka kwamanzi kwisigqubuthelo sekhonkrithi ngokukhawuleza kakhulu, thatha amanyathelo okufunxa ngokupheleleyo amanzi kwi-sprinkler, le ndlela yinkcitho yemithombo yamanzi kunye nokuphazamiseka kokusebenza, into ephambili kukuba amanzi aphezu komhlaba kuphela, kwaye ukufunxa kwangaphakathi akukagqitywa, ngoko ke isisombululo sengxaki yendlela yokudibanisa kwisigqubuthelo sekhonkrithi. Iarhente yokugcina amanzi kwi-cellulose ikhetha ngokubanzi i-hydroxypropyl methyl okanye i-methyl cellulose, iinkcukacha ze-viscosity phakathi kwe-20000 - 60000cps, yongeza i-2% - 3%. Ejikeleze, izinga lokugcina amanzi linganyuswa liye ngaphezulu kwe-85%, ukusetyenziswa kwesamente kwisigqubuthelo sekhonkrithi ngendlela yomgubo owomileyo oxutywe ngokulinganayo emanzini kunokuba.

(3) kwiplasta yestucco, iplasta yokubopha, iplasta efakwe ngaphakathi:

Ngenxa yophuhliso olukhawulezileyo lweshishini lokwakha, imfuno yabantu yezixhobo zokwakha ezintsha nayo iyanda. Ngenxa yokwanda kolwazi lwabantu malunga nokukhuselwa kwendalo kunye nokuphuculwa okuqhubekayo kokusebenza kakuhle kokwakha, iimveliso zegypsum zezinto ezisetyenziswa ngesamente ziye zaphuhliswa ngokukhawuleza. Okwangoku, iimveliso zegypsum eziqhelekileyo yi-brushing plaster, i-bonding plaster, i-embedded plaster, i-tile adhesive njalo njalo. I-brush plaster luhlobo lwezinto zokuplasta ezisemgangathweni ophezulu zodonga lwangaphakathi kunye nebhodi ephezulu, apho umphezulu wodonga uthambile kwaye ubushelelezi, akukho mgubo uwela kwaye i-substrate ibotshelelwe ngokuqinileyo ngaphandle kokuqhekeka nokuwa, kwaye inomsebenzi wokuthintela umlilo; i-bonding plaster luhlobo olutsha lwe-arhente yokubophelela ibhodi yokukhanya yokwakha, eyenziwe nge-gypsum njengezinto ezisisiseko kwaye yongezwe ngeentlobo ngeentlobo zezongezo, kwaye ifanelekile ukubophelela zonke iintlobo zezinto zodonga lwesakhiwo ezingaphiliyo, ezineempawu ze-non-toxic, i-nambitheka, i-coagulation ekhawulezayo kunye ne-bonding ekhawulezayo. Ifanelekile ukubopha phakathi kweentlobo ngeentlobo zezinto zokwakha ezingaphiliyo, ezinokuqina okungenatyhefu, okungenavumba, okukhawuleza, okukhawuleza, okuqina kunye nezinye iimpawu, kwaye sisixhobo esixhasayo ekwakheni iibhodi zokwakha kunye neebhloko; i-gypsum caulk sisizalisi sesithuba phakathi kweebhodi ze-gypsum kunye nesizalisi sokulungisa iindonga kunye neentanda.

Ezi mveliso zegypsum zinomsebenzi owahlukileyo, ukongeza kwigypsum kunye nezizalisi ezinxulumene nazo zidlala indima, ingxaki ephambili kukongeza izongezo ze-cellulose ether zidlala indima ephambili. Ekubeni igypsum yahlulwe yaba yi-gypsum engenamanzi kunye ne-semi-anhydrous gypsum, igypsum eyahlukeneyo ineempembelelo ezahlukeneyo ekusebenzeni kwemveliso, ngoko ke ukujiya, ukugcinwa kwamanzi kunye nokulibaziseka kwezixhobo zokwakha zegypsum kumisela umgangatho wezixhobo zokwakha zegypsum. Ingxaki eqhelekileyo yezi zinto kukuqhekeka nokuqhekeka, amandla okuqala awanakufikelelwa, ukusombulula le ngxaki, kukukhetha uhlobo lwe-cellulose kunye nokusetyenziswa kwe-retarder composite yengxaki, kule nkalo, ukhetho oluqhelekileyo lwe-methyl okanye i-hydroxypropylmethyl 30,000 - 60,000cps, ubungakanani bokongeza yi-1.5% - 2%. Phakathi, i-cellulose apho kugxilwe khona kukulukuhla kwamanzi okugcina ukugcinwa kwamanzi. Nangona kunjalo, kule nto, i-cellulose ether ayifikelelwanga, kufuneka yongezwe i-citric acid retarder, ukusetyenziswa okuxutyiweyo akuyi kuchaphazela amandla okuqala.

Izinga lokugcina amanzi ngokubanzi libhekisa kwimeko apho kungekho kufuma kwamanzi ngaphandle, ubungakanani bokulahleka kwamanzi ngokwendalo, ukuba udonga lomile, ukufunxwa kwamanzi kumphezulu osisiseko kunye nokuphuma kwamanzi ngokukhawuleza kakhulu, kuya kwenzeka okufanayo kwiidrama ezingenanto, ukuqhekeka. Le ndlela yokusebenzisa ukusetyenziswa okuxutyiweyo komgubo owomileyo, ukuba ukulungiswa kwesisombululo kunokubhekisa ekulungiseleleni isisombululo.

(4) I-thermal insulation mortar

I-thermal insulation mortar luhlobo olutsha lwezinto zokukhusela udonga lwangaphakathi, zizinto zodonga ezenziwe ngezinto zokukhusela ubushushu, i-mortar kunye ne-binder. I-cellulose kule nto, egxile ekubopheni, yonyusa indima yamandla. Ngokubanzi khetha i-methyl cellulose Ukuba i-viscosity ephezulu (10000cps okanye ngaphezulu), idosi ngokubanzi iphakathi kwe-2‰-3‰, kusetyenziswa indlela yokuxuba umgubo owomileyo.
