1)Isicelo esiphambili se-cellulose ether yezinto zokwakha zeklasi
Intsimi yezinto zokwakha yeyona ndawo iphambili efunekayoi-cellulose etherI-Cellulose ether ineempawu ezintle kakhulu ezifana nokuqina, ukugcinwa kwamanzi, kunye nokulibaziseka, ngoko ke isetyenziswa kakhulu ukuphucula nokwenza ngcono i-mortar exutyiweyo esele ilungisiwe (kubandakanya i-mortar exutyiweyo emanzi kunye ne-mortar exutyiweyo eyomileyo), imveliso ye-resin ye-PVC, ipeyinti ye-latex, i-putty, i-adhesive yethayile, Ukusebenza kweemveliso zezinto zokwakha kubandakanya i-thermal insulation mortar kunye nezinto zomgangatho kuzenza zihlangabezane neemfuno zokonga amandla kunye nokukhuselwa kwendalo, kuphucula ukusebenza kakuhle kokwakhiwa kwezakhiwo kunye nemihombiso, kwaye isetyenziswa ngokungathanga ngqo kulwakhiwo lwe-masonry plastering kunye nokuhombisa udonga lwangaphakathi nolwangaphandle lweentlobo ezahlukeneyo zeeprojekthi zokwakha. Ngenxa yobungakanani obukhulu botyalo-mali kwicandelo lobunjineli bokwakha, iintlobo ezahlukeneyo zeeprojekthi zokwakha ziyasasazeka, kukho iintlobo ezininzi, kwaye inkqubela phambili yokwakha iyahluka kakhulu, i-cellulose ether yeklasi yezinto zokwakha ineempawu zoluhlu olubanzi lwezicelo, imfuno enkulu yemarike, kunye nabathengi abasasazekileyo.
Phakathi kweemodeli eziphakathi neziphezulu zeHPMC yezixhobo zokwakha, iHPMC yezixhobo zokwakha enobushushu bejeli obuyi-75°C isetyenziswa kakhulu kwimota exutyiweyo eyomileyo nakwezinye iindawo. Inokumelana nobushushu obuphezulu kakhulu kunye nesiphumo esihle sokusetyenziswa. Ukusebenza kwayo kubushushu bejeli. Ayinakutshintshwa yiHPMC yezixhobo zokwakha kwi-60°C, kwaye abathengi bezona mveliso ziphezulu banemfuno ephezulu yozinzo lomgangatho wolu hlobo lwemveliso. Kwangaxeshanye, kunzima ngobuchwephesha ukuvelisa iHPMC enobushushu bejeli obuyi-75°C. Ubungakanani botyalo-mali lwezixhobo zemveliso bukhulu, kwaye umda wokungena uphezulu. Ixabiso lemveliso liphezulu kakhulu kuneleHPMC yezixhobo zokwakha enobushushu bejeli obuyi-60°C.
I-HPMC ekhethekileyo ye-PVC ekhethekileyo sisongezelelo esibalulekileyo kwimveliso ye-PVC. Nangona i-HPMC yongezwa kancinci kwaye ibangela inxalenye ephantsi yeendleko zemveliso ye-PVC, isiphumo sokusetyenziswa kwemveliso silungile, ngoko ke iimfuno zayo zomgangatho ziphezulu. Bambalwa abavelisi basekhaya nabangaphandle be-HPMC ye-PVC, kwaye ixabiso leemveliso ezingenisiweyo liphezulu kakhulu kuneleemveliso zasekhaya.
2)Indlela yoPhuhliso lweShishini le-Ether leCellulose Material Grade
①Uphuhliso oluzinzileyo lweshishini lokwakha lelizwe lam luyaqhubeka nokuqhuba imfuno yemarike ye-cellulose ether yezinga lezinto zokwakha.
Ngokwedatha ekhutshwe yi-National Bureau of Statistics, ngo-2021, izinga lokufudukela ezidolophini kwilizwe lam (inani labantu basezidolophini kubemi belizwe) liza kufikelela kwi-64.72%, ukwanda kweepesenti ezingama-0.83 xa kuthelekiswa nokuphela kuka-2020, kunye nokwanda xa kuthelekiswa nezinga lokufudukela ezidolophini lama-49.95% ngo-2010. Iipesenti ezili-14.77, nto leyo ebonisa ukuba ilizwe lam lingene kwinqanaba eliphakathi nelisekupheleni lokufudukela ezidolophini. Ngokunjalo, ukukhula kwemfuno iyonke kwimarike yezindlu zasekhaya nako kungene kwinqanaba elizinzileyo, kwaye umahluko wemfuno kwizixeko ezahlukeneyo uye wacaca ngakumbi. Imfuno yezindlu iyaqhubeka nokukhula. Kwixesha elizayo, ngokuhla kwenani lemveliso yelizwe lam kunye nokwanda kwenani lemveliso yeenkonzo, ukwanda kweendlela zengqesho eziguquguqukayo ezifana nokuvelisa izinto ezintsha kunye noshishino, kunye nophuhliso lweemodeli zeofisi eziguquguqukayo, iimfuno ezintsha ziya kubekwa phambili kurhwebo lwasezidolophini, indawo yokuhlala kunye nokulinganisela kwezindlu zomsebenzi. Iimfuno zemveliso yezindlu nezakhiwo ziya kwahlukahluka ngakumbi, kwaye ishishini lezindlu nezakhiwo zasekhaya zingene kwixesha lotshintsho nelokutshintsha.
Ubungakanani botyalo-mali kwishishini lokwakha, indawo yokwakha izindlu, indawo egqityiweyo, indawo yokuhombisa izindlu kunye notshintsho lwayo, inqanaba lengeniso yabemi kunye nemikhwa yokuhombisa, njl.njl., zezona zinto ziphambili ezichaphazela imfuno yemarike yasekhaya ye-cellulose ether yezinto zokwakha. Inkqubo yokufudukela kwabantu ezidolophini inxulumene kakhulu. Ukususela ngo-2010 ukuya ku-2021, ukugqitywa kotyalo-mali lwezindlu kunye nexabiso lemveliso yeshishini lokwakha kwilizwe lam ngokusisiseko ligcine umkhwa wokukhula ozinzileyo. Ngo-2021, isixa sokugqitywa kotyalo-mali lophuhliso lwezindlu kwilizwe lam yayiyi-14.76 trillion yuan, ukunyuka konyaka nonyaka kwe-4.35%; ixabiso lilonke lemveliso yeshishini lokwakha yayiyi-29.31 trillion yuan, ukunyuka kwe-11.04% ngonyaka nonyaka.
Ukususela ngo-2011 ukuya ku-2021, izinga lokukhula kwe-compound yonyaka kwindawo yokwakha izindlu kwishishini lokwakha lelizwe lam yi-6.77%, kwaye izinga lokukhula kwe-compound yonyaka kwindawo yokwakha yokugqitywa kwezindlu yi-0.91%. Ngo-2021, indawo yokwakha izindlu kwishishini lokwakha lelizwe lam iya kuba yi-9.754 yeebhiliyoni zeemitha zesikwere, kunye nezinga lokukhula konyaka nonyaka le-5.20%; indawo yokwakha egqityiweyo iya kuba yi-1.014 yeebhiliyoni zeemitha zesikwere, kunye nezinga lokukhula konyaka nonyaka le-11.20%. Imeko entle yokukhula kwishishini lokwakha lasekhaya iya kwandisa ukusetyenziswa kweemveliso zezinto zokwakha ezifana nodaka oluxutyiweyo olusele lulungisiwe, ukwenziwa kwe-resin ye-PVC, ipeyinti ye-latex, i-putty, kunye ne-adhesive yethayile, ngaloo ndlela iqhuba imfuno yemarike ye-cellulose ether ye-grade material grade.
②Ilizwe likhuthaza ngenkuthalo izixhobo zokwakha eziluhlaza ezimelwe ludaka oluxutyiweyo, kwaye indawo yophuhliso lwemarike yezinto zokwakha ze-cellulose ether iyanda ngakumbi.
I-mortar yinto edibanisayo esetyenziswa ekwakheni izitena. Yenziwe ngenxalenye ethile yesanti kunye nezinto zokudibanisa (isamente, intlama yelayimu, udongwe, njl.njl.) kunye namanzi. Indlela yendabuko yokusebenzisa i-mortar kukuxuba kwindawo, kodwa ngenkqubela phambili yetekhnoloji yeshishini lokwakha kunye nokuphuculwa kweemfuno zokwakha eziphucukileyo, ukusilela kwe-mortar yokuxuba kwindawo kuye kwabonakala ngakumbi, njengomgangatho ongaguqukiyo, inkunkuma enkulu yezinto, uhlobo olunye lwe-mortar, umgangatho ophantsi wokwakha okuphucukileyo kunye nokungcolisa okusingqongileyo, njl.njl.
Xa kuthelekiswa nodaka lokuxuba olukwindawo, inkqubo yodaka oluxutyiweyo luxutywa ngokunzulu, uthutho oluvaliweyo, uthutho lwepayipi yepompo, ukutshiza ngomatshini eludongeni, kunye neempawu zenkqubo yokuxuba okumanzi ngokwako, okunciphisa kakhulu ukuveliswa kothuli kwaye kulula ukwakhiwa ngoomatshini. Ngenxa yoko, udaka oluxutyiweyo luneengenelo zozinzo olusemgangathweni, iintlobo ezahlukeneyo, indawo yokwakha enobuhlobo, ukonga amandla kunye nokunciphisa ukusetyenziswa, kwaye luneenzuzo ezilungileyo zoqoqosho kunye nokusingqongileyo. Ukususela ngo-2003, urhulumente ukhuphe uthotho lwamaxwebhu omgaqo-nkqubo abalulekileyo ukukhuthaza ukuveliswa nokusetyenziswa kodaka oluxutyiweyo nokuphucula umgangatho woshishino lodaka oluxutyiweyo.
Okwangoku, ukusetyenziswa kwe-mortar exutyiweyo esele ilungisiwe endaweni ye-mortar exutyiweyo esele ilungisiwe sele yenye yeendlela ezibalulekileyo zokunciphisa ukukhutshwa kwe-PM2.5 kwishishini lokwakha. Kwixesha elizayo, ngenxa yokwanda kokunqongophala kwezixhobo zesanti kunye negrabile, iindleko zokusebenzisa isanti ngqo kwindawo yokwakha ziya kwanda, kwaye ukunyuka kweendleko zabasebenzi kuya kukhokelela ekunyukeni kancinci kweendleko zokusetyenziswa kwe-mortar exutyiweyo esele ilungisiwe, kwaye imfuno ye-mortar exutyiweyo esele ilungisiwe kwishishini lokwakha iya kuqhubeka ikhula. Ubungakanani be-cellulose ether yeklasi yezinto zokwakha kwi-mortar exutyiweyo esele ilungisiwe ngokubanzi ibandakanya malunga ne-2/10,000. Ukongeza i-cellulose ether kunceda ukwenza i-mortar exutyiweyo esele ilungisiwe ibe nkulu, ukugcina amanzi kunye nokuphucula ukusebenza kokwakha. Ukwanda kuya kuqhuba nokukhula kwemfuno ye-cellulose ether yeklasi yezinto zokwakha.
