I-Cellulose yokwakha i-additive esetyenziswa kakhulu kwimveliso yokwakha. I-Cellulose yokwakhiwa isetyenziswa kakhulu kwi-powder mortar eyomileyo. Ukongezwa kwe-cellulose ether kuphantsi kakhulu, kodwa kunokuphucula kakhulu ukusebenza kodaka olumanzi kwaye kuchaphazele ukwakhiwa komdaka. Ukusebenza kufuneka kuthathelwe ingqalelo ekusetyenzisweni. Ngoko ke ziziphi iipropati ezibonakalayo ze-cellulose zokwakha, kwaye yintoni inkqubo yokwakhiwa kwe-cellulose yokwakha? Ukuba awuyazi kakhulu malunga neepropati kunye nenkqubo yokwakha ye-cellulose yokwakha, makhe sijonge kunye.
Zeziphi iimpawu ezibonakalayo zeselulosi xa kusakhiwa:
1. Ukubonakala: umgubo omhlophe okanye omhlophe.
2. Ubungakanani besuntswana; ireyithi yokupasa ye-100 mesh inkulu kuno-98.5%; ireyithi yokupasa ye-80 mesh inkulu kune-100%.
3. Ubushushu beCarbonization: 280-300 ° C
4. Ubuninzi obubonakalayo: 0.25-0.70 / cm3 (ngokuqhelekileyo malunga ne-0.5g / cm3), ubunzima obuthile 1.26-1.31.
5. Ubushushu bokutshintsha umbala: 190-200 ° C
6. Uxinzelelo lomphezulu: I-2% isisombululo samanzi ngu-42-56dyn / cm.
7. I-Soluble emanzini kunye nezinye izinyibilikisi, ezifana nomlinganiselo ofanelekileyo we-ethanol / amanzi, ipropanol / amanzi, i-trichloroethane, njl. Izisombululo ezinamanzi zisebenza phezulu. Ukucaca okuphezulu, ukusebenza okuzinzileyo, imilinganiselo eyahlukeneyo yeemveliso ezinobushushu obuhlukeneyo bejel, utshintsho lwe-solubility kunye ne-viscosity, i-viscosity ephantsi, i-solubility enkulu, imilinganiselo eyahlukeneyo ye-HPMC inomahluko othile ekusebenzeni, kwaye ukuchithwa kwe-HPMC emanzini akuchaphazeli ixabiso le-pH.
8. Ngokunciphisa umxholo we-methoxyl, i-gel point iyanda, i-solubility yamanzi ye-HPMC iyancipha, kwaye umsebenzi ongaphezulu uyancipha.
9. I-HPMC nayo ineempawu zokukwazi ukuqina, ukuxhathisa ityuwa, umgubo ophantsi wothuthu, ukuzinza kwe-PH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, ipropati egqwesileyo yokwenza ifilimu, kunye noluhlu olubanzi lokuchasa i-enzyme, i-dispersibility kunye nokubambisana.
Yintoni inkqubo yokwakhiwa kweselulosi yokwakhiwa:
1. Iimfuno zenqanaba lesiseko: Ukuba ukunamathela kwodonga lwesiseko alukwazi ukuhlangabezana neemfuno, indawo yangaphandle yodonga lwesiseko kufuneka ihlambuluke ngokucokisekileyo, kwaye i-agent ye-interface kufuneka isetyenziswe ukunyusa umthamo wokugcinwa kwamanzi eludongeni kwaye ngaloo ndlela ikhulise amandla okudibanisa phakathi kwodonga kunye nebhodi ye-polystyrene.
2. Umgca wolawulo lokudlala: vula imigca yokulawula ethe tyaba kunye nethe nkqo yeengcango zangaphandle kunye neefestile, amajoyina okwandisa, amalunga okuhlobisa, njl njl eludongeni.
3. Xhoma umgca wereferensi: Zixhome iingcingo zentsimbi zereferensi ezithe nkqo kwiikona ezinkulu (iikona zangaphandle, iikona zangaphakathi) zodonga lwangaphandle lwesakhiwo kunye nezinye iindawo eziyimfuneko, kwaye uxhome imigca ethe tyaba kwindawo efanelekileyo kumgangatho ngamnye ukuze ulawule ukuqina kunye nokuthe tyaba kwebhodi ye-polystyrene.
4. Ukulungiswa kwe-polymer adhesive mortar: Esi sixhobo singumdaka owenziwe nge-polymer adhesive, omele usetyenziswe ngokweemfuno zale mveliso, ngaphandle kokongeza ezinye izinto, ezifana nesamente, isanti kunye nezinye iipolymers.
5. Ncamathelisa ilaphu legridi elibhukuqiweyo: Zonke iindawo eziveziweyo kwicala lebhodi yepolystyrene encanyathelisweyo (njengamajoyinti okwandisa, iindawo zokuhlala zesakhiwo, iintambo zobushushu kunye nezinye iintambo kumacala omabini, iingcango kunye neefestile) kufuneka ziphathwe ngelaphu legridi. .
6. Ibhodi ye-polystyrene enamathelayo: Qaphela ukuba i-cut is perpendicular to the surface board. Ukuphambuka kobungakanani kufuneka kufezekise iimfuno zemimiselo, kwaye amajoyina ebhodi ye-polystyrene akufanele ashiywe kwiikona ezine zomnyango kunye nefestile.
7. Ukulungiswa kweehange: inani leehange lingaphezulu kwe-2 ngemitha yesikwere (yandiswe ngaphezu kwe-4 kwizakhiwo eziphakamileyo).
8. Lungisa udaka lokutyabeka: Lungisa udaka lokutyabeka ngokomlinganiselo onikwe ngumenzi, ukuze kuphunyezwe umlinganiselo ochanekileyo, ukuvuselela oomatshini besibini, kunye nokuxutywa.
Phakathi kweentlobo ze-cellulose ezisetyenziselwa ukwakhiwa, i-cellulose ether esetyenziswa yi-hydroxypropyl methylcellulose kwi-powder mortar eyomileyo i-hydroxypropyl methylcellulose ether. I-Hydroxypropyl methylcellulose ikakhulu idlala indima yokugcinwa kwamanzi, ukuqina kunye nokuphucula ukusebenza kokwakhiwa kwi-powder mortar.
