I-Cellulose ether iyisengezo esiyinhloko se-gypsum ekhokhiwe ukukhanya, edlala indima ebalulekile ku-gypsum ekhokhiwe ukukhanya. Ilungelo alizwani nesisekelo semikhiqizo ye-cellulose ether ye-HPMC, ingangena ngokushesha kuzo zonke izinhlobo zemikhiqizo ye-gypsum futhi ngeke ikhiqize iqoqo, i-porosity yokunamathisela i-gypsum ngemva kokuphulukiswa ngaphandle komthelela omubi, ukuze kuqinisekiswe ukusebenza kokuphefumula kwe-gypsum yokunamathisela. , isenzo sokuhlehlisa kodwa hhayi sinethonya kumakristalu e-gypsum akhula, ngamandla afanele amanzi e-viscous ukuze kuqinisekiswe ikhono lokubopha izinto ezibonakalayo, endaweni ephansi Kuthuthukisa kakhulu ukusebenza kokwakhiwa kwemikhiqizo ye-gypsum, okwenza kube lula ukusabalalisa ngaphandle kokunamathela kumathuluzi.
Njengoba nonke nazi, eminyakeni yamuva nje, ngokuthuthukiswa kwezwe kanye nokulungisa izinqubomgomo, ukuthuthukiswa kwezinto zokwakha eziluhlaza zokuvikela imvelo sekuphenduke indawo eshisayo, njengoba impahla yokufaka yasendlini yezinto ezintsha, i-gypsum yokufaka i-plastering iqokonyiswa kakhulu, i-gypsum plastering iyanda. esikhundleni sikasimende nosimende izinto ezintsha ukonga amandla, ukuvikelwa kwemvelo, umnotho, kokubili amandla usimende, futhi uma kuqhathaniswa usimende ukuvikelwa kwemvelo okunempilo, isikhathi eside, Amandla Adhesive mkhulu, akulula ukuba impushana, hhayi ngokuqhekeka, hhayi ezingenalutho. isigubhu, hhayi impushana eyehlayo nezinye izinzuzo, kulula ukuyisebenzisa, ukonga izindleko, i-plaster gypsum ekhanyayo isekelwe ikakhulukazi ekwakheni i-plaster powder njengento eyinhloko, ukukhanyisa i-perlite noma ubuhlalu bengilazi njenge-aggregate, engeza izinto ezihlukahlukene ze-plaster entsha.
I-cellulose ether Inezinzuzo ezilandelayo:
Okokuqala, lungisa umswakama womoya, lapho umswakama wangaphandle uphakeme kunomswakama ohambisanayo we-plaster plaster, ngoba ukucindezela komhwamuko wangaphandle kuphezulu kunokucindezela kwawo okugcwele umhwamuko, kukhuthaze ukusebenza kwangaphakathi kokungena kwamanzi, ukuze kubambezeleke ukukhuphuka umswakama; Uma umswakamo wangaphandle uphansi kunomswakama ohambisanayo wegypsum ekhonkolowe, umfutho womhwamuko wangaphandle uphansi kunomfutho wawo womhwamuko ogcwele, obangela ukuhwamuka kwama-molecule wamanzi angaphakathi. Ngakho-ke, ingadlala indima yokulungisa nokulawula umswakama.
Okwesibili, ukungasebenzi kahle kwelangabi. Isisindo samangqamuzana e-dihydrous gypsum singu-172, kanti isisindo samangqamuzana samanzi singu-18. Uma indlu engu-100m2 ihlangana nomlilo, lapho izinga lokushisa lifinyelela ku-110 ℃ noma ngaphezulu, i-dihydrous gypsum izokhulula ngokushesha amanzi ayikristalu ku-semihydrous gypsum bese ishintsha ngokuqhubekayo. ibe yi-anhydrous gypsum, engakhulula amanzi angama-560kg. Amanzi angamunca ukushisa okuningi ohlelweni lokuhwamuka. Ingavimbela ngokuphumelelayo ukukhuphuka okusheshayo kwezinga lokushisa legumbi futhi ithuthukise amathuba okuphunyuka.
Okwesithathu, ukuvikelwa kwemvelo okuluhlaza. I-Gypsum ngemuva kokwelashwa okungenabungozi, ayiqukethe ukungcola okuncibilikayo, ukusetshenziswa kwezinto zejeli ezingaphili, izithasiselo ziyimikhiqizo yokuvikela imvelo, eyenziwe nge-plaster gypsum ekhanyayo ayikhiphi i-formaldehyde nezinye izinto eziyingozi, ukuvikelwa kwemvelo okuluhlaza, ukuphepha nokuphepha.
Okwesine, ukwahlukanisa ukushisa, ukonga amandla, ukumuncwa komsindo, ukumelana nomthelela. I-thermal conductivity ye-plastering plaster ingu-0.17W / (MK), ngakho-ke ukushisa okushisayo kwe-plastering plaster kungamaphesenti angu-20 odaka lwendabuko lokunamathisela usimende, olunomphumela othile wokushisa oshisayo futhi onganciphisa ukusetshenziswa kwamandla kwezakhiwo. I-Plastering gesso isenqubweni ye-condense, ingaphakathi likhiqiza igebe elincane, ngoba lokhu kunganciphisa ingcindezi yomsindo, kungavimbela amandla omsindo ukuthi aqhume futhi, angaguqula amandla omsindo abe amandla okushisa, abe nokusebenza kahle kokufakwa komsindo ngakho. Ngenxa yesakhiwo esinezimbotshana ngemva kokujiya, ingakwazi ukumunca ngempumelelo amandla omthelela, ngakho-ke ngeke iqhekeke futhi siwe lapho ingaphansi komthelela.
Ukunamathisela i-gypsum nge-cellulose ether ikakhulukazi kunezici ezilandelayo:
1, ukwakhiwa okuhle kakhulu: ukukhuhla kulula, okubushelelezi, kungaba ukubumba, ngepulasitiki.
2, thuthukisa izinga lokumboza ngodaka: uma kuqhathaniswa ne-cellulose ether efanayo, izinga lokumboza lenyuke kakhulu.
I-3, ukusebenza okuhle kakhulu kwe-anti-droop: ungqimba oluqinile olukhuhla ukwakhiwa okukodwa akugelezi kulenga, izikhathi ezingaphezu kwezimbili (ngaphezu kuka-3cm) ukukhuhla akuconsi, ipulasitiki enhle kakhulu.
I-4, izinga elihle kakhulu lokugcinwa kwamanzi: ukwandisa isikhathi sokusebenza kwesisekelo se-gypsum, thuthukisa ukumelana nesimo sezulu sesisekelo se-gypsum, ukhuphule amandla okubopha wesisekelo se-gypsum nesisekelo, ukusebenza okuhle kakhulu kokubopha okumanzi, ukunciphisa umlotha womhlabathi.
I-5, ukuhambisana okuqinile: kufanelekile kuzo zonke izinhlobo zesisekelo se-gypsum, ukunciphisa isikhathi sokuguga se-gypsum, ukunciphisa izinga lokunciphisa okomisa, udonga akulula ukukhipha isigubhu, ukuqhekeka.
6, inkambu yesicelo kanye nenani: i-gypsum ye-plaster ekhanyayo ephansi, umthamo onconywayo ngu-0.18% - 0.25%.
Ukunamathisela i-gypsum nge-cellulose ether kwenziwa ngekhwalithi ephezulu kakotini ehlanjululwe ngokusabela kwe-etherification, i-non-ionic cellulose ether, izakhiwo ezinzile ngokomzimba, ngeke kukhiqize ukusabela kwamakhemikhali nezinye izinto zokusetshenziswa futhi kukhiqize izinto eziyingozi, ezinobungani bemvelo, ezingenamthelela empilweni yomuntu, e-plastering gypsum iwuhlobo lwezithasiselo zokonga amandla aluhlaza, i-KIMA ibilokhu ingumqondo wokuvikelwa kwemvelo eluhlaza kanye nokongiwa kwamandla emikhiqizweni nasekuphathweni kwenkampani, sikhuthaza ukuthuthukiswa okusimeme, ngokuphendula ucingo lukazwelonke, izintaba eziluhlaza ziyigolide nesiliva. ezintabeni, i-KIMA izosebenzisa imikhiqizo engcono kakhulu ye-cellulose ether ukusiza umhlaba ukuthi udale ukuvikelwa kwemvelo okuluhlaza okokunamathisela odongeni lwasendlini.
