I-Cellulose yokwakha sisongezelelo esisetyenziswa kakhulu kwimveliso yokwakha. I-Cellulose yokwakha isetyenziswa kakhulu kwi-mortar eyomileyo. Ukongezwa kwe-cellulose ether kuphantsi kakhulu, kodwa kunokuphucula kakhulu ukusebenza kwe-mortar emanzi kwaye kuchaphazele ukwakhiwa kwe-mortar. Ukusebenza kufuneka kunikwe ingqalelo ekusetyenzisweni. Ngoko ke zithini iimpawu zomzimba ze-cellulose zokwakha, kwaye yintoni inkqubo yokwakha ye-cellulose yokwakha? Ukuba awazi okuninzi malunga neempawu kunye nenkqubo yokwakha ye-cellulose yokwakha, makhe sijonge kunye.
Zithini iipropati zomzimba ze-cellulose zokwakha:
1. Inkangeleko: umgubo omhlophe okanye omhlophe qhwa.
2. Ubungakanani bezinto ezincinci; izinga lokupasa le-100 mesh lingaphezulu kwe-98.5%; izinga lokupasa le-80 mesh lingaphezulu kwe-100%.
3. Ubushushu beCarbonization: 280-300°C
4. Uxinano olubonakalayo: 0.25-0.70/cm3 (ngesiqhelo malunga ne-0.5g/cm3), ubunzima obuthile 1.26-1.31.
5. Ubushushu bokutshintsha kombala: 190-200°C
6. Uxinzelelo lomphezulu: isisombululo samanzi se-2% yi-42-56dyn/cm.
7. Inyibilika emanzini nakwezinye izinyibilikisi, ezifana nomlinganiselo ofanelekileyo we-ethanol/amanzi, i-propanol/amanzi, i-trichloroethane, njl. Izisombululo zamanzi zisebenza kumphezulu. Ukukhanya okuphezulu, ukusebenza okuzinzileyo, iinkcukacha ezahlukeneyo zeemveliso zinobushushu obahlukeneyo bejeli, utshintsho lokunyibilika kunye ne-viscosity, kokukhona i-viscosity iphantsi, kokukhona ukunyibilika kukhulu, iinkcukacha ezahlukeneyo ze-HPMC zinomahluko othile ekusebenzeni, kwaye ukunyibilika kwe-HPMC emanzini akuchaphazeleki lixabiso le-pH.
8. Ngokuncitshiswa komxholo we-methoxyl, inqaku lejeli liyanda, ukunyibilika kwamanzi kwe-HPMC kuyancipha, kwaye nomsebenzi womphezulu nawo uyancipha.
9. I-HPMC ikwanazo neempawu zokuba namandla okuqina, ukumelana netyuwa, umgubo womlotha ophantsi, uzinzo lwe-PH, ukugcinwa kwamanzi, uzinzo olunemilinganiselo, ipropati entle yokwenza ifilimu, kunye noluhlu olubanzi lokumelana nee-enzyme, ukusasazeka kunye nokuhambelana.
Iyintoni inkqubo yokwakha i-cellulose yokwakha:
1. Iimfuno zenqanaba elisezantsi: Ukuba ukunamathela kodonga olusezantsi akunakuhlangabezana neemfuno, umphezulu ongaphandle wodonga olusezantsi kufuneka ucocwe kakuhle, kwaye kufuneka kusetyenziswe i-interface agent ukwandisa amandla okugcina amanzi odonga ngaloo ndlela kuphuculwe amandla okubopha phakathi kodonga kunye nebhodi ye-polystyrene.
2. Umgca wokulawula umdlalo: vula imigca yokulawula ethe tye nethe nkqo yeengcango neefestile zangaphandle, iindawo zokwandisa, iindawo zokuhombisa, njl.njl. eludongeni.
3. Xhoma umgca wesalathiso: Xhoma iingcingo zentsimbi zesalathiso ezithe nkqo kwiikona ezinkulu (iikona zangaphandle, iikona zangaphakathi) zeendonga zangaphandle zesakhiwo nakwezinye iindawo ezifunekayo, kwaye uxhome imigca ethe tye kwiindawo ezifanelekileyo kumgangatho ngamnye ukulawula ukuma nkqo kunye nokuba sithambe kwebhodi yepolystyrene.
4. Ukulungiswa kwe-polymer adhesive mortar: Le nto yi-polymer adhesive mortar elungiselelweyo, ekufuneka isetyenziswe ngokweemfuno zale mveliso, ngaphandle kokongeza ezinye izinto, ezifana nesamente, isanti kunye nezinye ii-polymers.
5. Ncamathisela ilaphu legridi elijikiweyo: Zonke iindawo ezivezwe ecaleni kwebhodi yepolystyrene encanyathiselweyo (ezifana neendawo zokwandisa, iindawo zokudibanisa izakhiwo, iindawo zokudibanisa ubushushu kunye nezinye izinto zokugquma kumacala omabini, iingcango kunye neefestile) kufuneka ziphathwe ngelaphu legridi.
6. Ibhodi ye-polystyrene enamathelayo: Qaphela ukuba isikwe sime nkqo kumphezulu webhodi. Ukuphambuka kobukhulu kufuneka kuhambelane neemfuno zemimiselo, kwaye iindawo ezidityanisiweyo zebhodi ye-polystyrene akufuneki zishiywe kwiikona zone zomnyango nefestile.
7. Ukulungiswa kwee-ankile: inani lee-ankile lingaphezulu kwe-2 nge-square meter (linyuswe laya kutsho ngaphezulu kwe-4 kwizakhiwo eziphakamileyo).
8. Lungisa udaka lokuplasta: Lungisa udaka lokuplasta ngokwesilinganiselo esinikwe ngumvelisi, ukuze kufezekiswe umlinganiselo ochanekileyo, ukuxutywa kwesibini ngoomatshini, kwanokuxuba.
Phakathi kweentlobo ze-cellulose ezisetyenziswa ekwakheni, i-cellulose ether esetyenziswa yi-hydroxypropyl methylcellulose kwi-dry powder mortar ikakhulu yi-hydroxypropyl methylcellulose ether. I-Hydroxypropyl methylcellulose idlala indima yokugcina amanzi, ukuqina kunye nokuphucula ukusebenza kokwakha kwi-dry powder mortar.
