1)Ukusetyenziswa okuphambili kwezinto zokwakha kwibakala le-cellulose ether
Intsimi yezinto zokwakha yinkalo yemfuno ephambili yei-cellulose ether. I-Cellulose ether ineempawu ezibalaseleyo ezifana nokutyeba, ukugcinwa kwamanzi, kunye nokunciphisa, ngoko ke isetyenziselwa ngokubanzi ukuphucula kunye nokuphucula udaka oluxutywe kakuhle (kubandakanya udaka oluxutywe nodaka kunye nodaka oluxubeneyo), ukuveliswa kwe-PVC resin, ipeyinti ye-latex, i-putty, i-tile yokuncamathelisa i-tile, Ukusebenza kweemveliso zezinto zokwakha ezibandakanya udaka lokufakelwa kwe-thermal kunye nezixhobo zomgangatho kubenza bahlangabezane neemfuno zogcino lwamandla kunye nokhuseleko lokusingqongileyo, kuphucula ukusebenza kakuhle kolwakhiwo lwezakhiwo kunye nemihombiso, kwaye isetyenziswa ngokungangqalanga kulwakhiwo lokutyatyekwa ngamatye kunye nokuhombisa udonga lwangaphakathi nangaphandle lweentlobo ezahlukeneyo zeeprojekthi zokwakha. Ngenxa yomlinganiselo omkhulu wotyalo-mali kwintsimi yobunjineli bokwakha, iintlobo ezahlukeneyo zeeprojekthi zokwakha zisasazwa, kukho iintlobo ezininzi, kwaye inkqubela phambili yokwakha iyahluka kakhulu, umgangatho wezinto zokwakha i-cellulose ether ineempawu zoluhlu olubanzi lwesicelo, imfuno enkulu yemarike. , kunye nabathengi abathe saa.
Phakathi kwemodeli ephakathi kunye neyokugqibela yezinto zokwakha zebanga le-HPMC, ibakala lezinto zokwakha ze-HPMC kunye nokushisa kwe-gel ye-75 ° C isetyenziswa kakhulu kumdaka oxubekileyo kunye nezinye iindawo. Inokumelana nobushushu obuphezulu kunye nesiphumo esihle sesicelo. Ukusebenza kwayo kwesicelo yiqondo lokushisa le-gel Ayinakuthathelwa indawo yibakala lezinto zokwakha ze-HPMC kwi-60 ° C, kwaye abathengi abaphezulu banemfuno ephezulu ekuzinzeni komgangatho wolu hlobo lwemveliso. Ngaxeshanye, kunzima ngokobuchule ukuvelisa iHPMC enobushushu bejeli obungama 75°C. Umlinganiselo wotyalo-mali wezixhobo zokuvelisa mkhulu, kwaye umda wokungena uphezulu. Ixabiso lemveliso liphezulu kakhulu kunelo lomgangatho wokwakha we-HPMC kunye nobushushu bejeli obungama-60°C.
I-HPMC ephezulu ye-PVC-specific is a additive ebalulekileyo kwimveliso ye-PVC. Nangona i-HPMC yongezwa kwisixa esincinci kwaye i-akhawunti yomlinganiselo ophantsi weendleko zokuvelisa i-PVC, umphumo wesicelo semveliso ulungile, ngoko ke iimfuno zayo zomgangatho ziphezulu. Bambalwa abavelisi basekhaya nabangaphandle be-HPMC ye-PVC, kwaye ixabiso leemveliso ezivela kumazwe angaphandle liphezulu kakhulu kunelo leemveliso zasekhaya.
2)UPhuhliso lweMathiriyeli yoKwakha kwiBanga leSelulosi ye-Etere yoShishino
①Uphuhliso oluzinzileyo lweshishini lolwakhiwo lwelizwe lam luyaqhubeka nokuqhuba imfuno yentengiso yezinto zokwakha zomgangatho we-cellulose ether.
Ngokweenkcukacha ezikhutshwe yi-National Bureau of Statistics, ngo-2021, izinga lokufudukela kwabantu ezidolophini kwilizwe lam (umlinganiselo wabemi basezidolophini kubemi besizwe) liya kufikelela kuma-64.72%, ukonyuka nge-0.83 yeepesenti xa kuthelekiswa nokuphela kuka-2020, kwaye ukunyuka xa kuthelekiswa nezinga lokufudukela kwabantu ezidolophini ngama-49.95% ngowama-2010. ingene kumanqanaba aphakathi nasekupheleni kokufudukela kwabantu ezidolophini. Ngokuhambelanayo, ukukhula kweemfuno ezipheleleyo kwimarike yezindlu zasekhaya kuye kwangena kwinqanaba elizinzileyo, kwaye ukuhlukana kweemfuno kwizixeko ezahlukahlukeneyo kuye kwacaca ngakumbi. Imfuno yezindlu iyaqhubeka isanda. Kwixesha elizayo, ngokuhla komlinganiselo weshishini lemveliso yelizwe lam kunye nokwanda komlinganiselo weshishini leenkonzo, ukwanda kweefomu zengqesho ezibhetyebhetye ezifana nokuveliswa kwezinto ezintsha kunye noshishino, kunye nophuhliso lwemodeli yeofisi ebhetyebhetye, iimfuno ezintsha ziya kuba ibeke phambili urhwebo lwasezidolophini, indawo yokuhlala kunye nebhalansi yezindlu zemisebenzi. Iimveliso ze-real estate iimfuno zeshishini ziya kuba zintlukwano ngakumbi, kwaye imboni yezindlu zasekhaya kunye neshishini lokwakha lingene kwixesha lenguqu kunye nenguqu.
Ubungakanani botyalo-mali lweshishini lokwakha, indawo yokwakha ye-real estate, indawo egqityiweyo, indawo yokuhlobisa izindlu kunye neenguqu zayo, inqanaba lengeniso yabahlali kunye nemikhwa yokuhlobisa, njl., zizinto eziphambili ezichaphazela imfuno yemarike yasekhaya yokwakha. umgangatho wezinto eziphathekayo cellulose ether. Inkqubo yokufudukela ezidolophini inxulumene ngokusondeleyo. Ukusukela ngo-2010 ukuya kowama-2021, ukugqitywa kotyalo-mali lwelizwe lam kunye nexabiso lemveliso yolwakhiwo lugcine ukukhula okuzinzileyo. Ngo-2021, utyalo-mali olugqityiweyo lwelizwe lam lophuhliso lwezindlu nezindlu lwaluyi-14.76 yetriliyoni yeeyuan, ukunyuka konyaka-nyaka nge-4.35%; Ixabiso lemveliso yoshishino lokwakha lilonke lalingama-29.31 eebhiliyoni zeeyuan, ukwanda nge-11.04% unyaka nonyaka.
Ukusukela ngo-2011 ukuya kowama-2021, umyinge wokukhula komndilili wonyaka wokukhula kolwakhiwo lwezindlu kushishino lolwakhiwo lwelizwe lam yi-6.77%, kwaye umndilili wokukhula komndilili wonyaka wokugqitywa kwendlu yi-0.91%. Ngo-2021, indawo yolwakhiwo lwezindlu kwishishini lolwakhiwo lwelizwe lam liya kuba yi-9.754 yeebhiliyoni zeemitha zesikwere, kunye nezinga lokukhula konyaka-ngonyaka we-5.20%; indawo yokwakha egqityiweyo iya kuba yi-1.014 yeebhiliyoni zeemitha zesikwere, kunye nezinga lokukhula ngonyaka-11.20%. Indlela yokukhula encomekayo kushishino lolwakhiwo lwasekhaya iya kwandisa ukusetyenziswa kweemveliso zemathiriyeli yokwakha ezinje ngodaka oluxutyiweyo, ukwenziwa kweresin yePVC, ipeyinti yelatex, iputty, kunye nokunamatheliswa kweethayile, ngaloo ndlela iqhuba imfuno yentengiso yomgangatho wokwakha we-cellulose ether.
②Ilizwe likhuthaza ngenkuthalo izinto zokwakha eziluhlaza ezimelwe ngodaka oluxutyiweyo, kwaye indawo yokuphuhlisa imarike yezinto zokwakha ibakala le-cellulose ether yandiswa ngakumbi.
Udaka yinto yokudibanisa esetyenziswa ekwakheni izitena. Iqulunqwe ngumlinganiselo othile wesanti kunye nezixhobo zokubopha (isamente, i-lime paste, udongwe, njl.) kunye namanzi. Indlela yemveli yokusebenzisa udaka kukuxutywa kwesiza, kodwa ngenkqubela yetekhnoloji yeshishini lokwakha kunye nokuphuculwa kweemfuno zokwakha eziphucukileyo, iziphene zodaka lokuxuba kwisiza ziye zaphawuleka ngakumbi, njengomgangatho ongazinzanga, inkunkuma enkulu. izixhobo, uhlobo olulodwa lodaka, iqondo eliphantsi lolwakhiwo oluphucukileyo kunye nokungcolisa imo engqongileyo, njl.
Xa kuthelekiswa nodaka lokuxuba kwisiza, inkqubo yodaka oluxutyiweyo olulungele ukuxutywa luxutywe, ukuthuthwa okuvaliweyo, ukuthuthwa kombhobho wempompo, ukutshiza ngomatshini eludongeni, kunye neempawu zenkqubo yokuxuba okumanzi ngokwawo, okunciphisa kakhulu ukuveliswa kothuli kwaye elungele ukwakhiwa koomatshini. Ngoko ke udaka oluLungileyo oluxutyiweyo luneenzuzo zozinzo olusemgangathweni olulungileyo, iintlobo ngeentlobo ezityebileyo, imeko-bume yokwakha enobuhlobo, ukonga umbane kunye nokunciphisa ukusetyenziswa, kwaye ineenzuzo ezilungileyo zoqoqosho nokusingqongileyo. Ukususela ngo-2003, urhulumente ukhuphe uluhlu lwamaxwebhu abalulekileyo omgaqo-nkqubo ukukhuthaza ukuveliswa kunye nokusetyenziswa kodaka olusele luxutywe nokuphucula umgangatho woshishino lodaka olusele luxutywe.
Okwangoku, ukusetyenziswa kodaka olusele luxutywe endaweni yodaka oluxubeneyo lwendawo luye lwaba yenye yeendlela ezibalulekileyo zokunciphisa ukukhutshwa kwe-PM2.5 kushishino lokwakha. Kwixesha elizayo, ngokunyuka kokunqongophala kwemithombo yesanti kunye negrabile, iindleko zokusebenzisa ngokuthe ngqo isanti kwindawo yokwakha ziya kwanda, kwaye ukunyuka kweendleko zabasebenzi kuya kukhokelela ekunyukeni kancinci kweendleko zokusetyenziswa kodaka oluxutywe kwisiza, kunye nemfuno yodaka olusele luxutywe kushishino lokwakha luya kuqhubeka nokukhula. Isixa sezinto zokwakha zebakala le-cellulose ether kudaka olulungele ukuxuba ngokubanzi lubalelwa malunga ne-2/10,000. Ukongeza i-cellulose ether inceda ukutyebisa udaka oluxutyiweyo, ukugcina amanzi kunye nokuphucula ukusebenza kolwakhiwo. Ukonyuka kuya kuqhuba nokukhula kwemfuno yemathiriyeli yomgangatho we-cellulose ether.
