(1) IHydroxypropyl methylcellulose (HPMC) yohlulwe ibe luhlobo oluqhelekileyo (uhlobo olunyibilikayo olushushu) kunye nohlobo lwamanzi abandayo olukhawulezileyo:
Uhlobo oluqhelekileyo, i-clumps emanzini abandayo, kodwa inokusasazeka ngokukhawuleza emanzini ashushu kwaye iphele emanzini ashushu.Xa iqondo lobushushu lehla ukuya kwiqondo elithile lobushushu, i-viscosity iya kubonakala kancinane ide yenze i-colloid ebonakalayo ebonakalayo.Isizathu sokudibana nezigaqa zamanzi abandayo kukuba: i-cellulose powder yangaphandle idibana namanzi abandayo, ngokukhawuleza iba yi-viscous, ijiye ibe yi-colloid ebonakalayo, kwaye i-cellulose ngaphakathi ijikelezwe yi-colloid ngaphambi kokuba idibane namanzi, kwaye isengumgubo. ifomu., kodwa ngokuthe ngcembe iyanyibilika.Iimveliso eziqhelekileyo azidingi ukusebenzisa amanzi atshisayo kwizicelo eziphathekayo, kuba i-putty powder okanye i-mortar i-powder eqinile.Emva kokuxuba okomileyo, i-cellulose ihlukaniswe nezinye izinto.Xa idibana namanzi, iya kuba yi-viscous ngokukhawuleza kwaye ayiyi kubumba iqela.
Imveliso ekhawulezileyo isasazeka ngokukhawuleza xa idibana namanzi abandayo kwaye iyanyamalala emanzini.Ngeli xesha, i-liquid ayinayo i-viscosity, kuba i-HPMC ihlakazekile kuphela emanzini ngaphandle kokuchithwa kwangempela.Ukususela malunga nemizuzu emi-2, i-viscosity ye-liquid iyanda ngokuthe ngcembe, isenza i-colloid ebonakalayo ebonakalayo.
(2) Umda wokusetyenziswa kohlobo oluqhelekileyo kunye nohlobo olukhawulezileyo: uhlobo olukhawulezileyo lusetyenziswa ikakhulu kwiglu engamanzi, izinto zokuthambisa, kunye nesicoci sempahla.Ngenxa yokuba umphezulu we-cellulose esheshayo uphathwe nge-dialdehyde, ukugcinwa kwamanzi kunye nokuzinza akulungile njengemveliso eqhelekileyo.Ngoko ke, kwipowder eyomileyo efana ne-putty powder kunye nodaka, sincoma iimveliso eziqhelekileyo.
Indlela yokukhetha i-viscosity efanelekileyo ye-cellulose:
1. Okokuqala, kufuneka siqonde indima ye-cellulose ether: ukugcinwa kwamanzi kunye nokuqina.
2. Ishishini linokuthi ngokuqhelekileyo i-100,000 viscosity, i-150,000 viscosity, kunye ne-200,000 viscosity.Ithetha ntoni le milinganiselo?Yintoni impembelelo yeeyunithi ezahlukeneyo zokulinganisa kwimveliso?
(1) Ukugcina amanzi
Ukusebenza kokugcinwa kwamanzi kwanda ngokunyuka kwe-viscosity, kodwa ngokwemiqathango yeemarike, xa i-viscosity ye-cellulose idlula i-100,000, ukugcinwa kwamanzi kuyanda kunye ne-viscosity.
(2) Ukujiya
Ngokuqhelekileyo, xa umxholo osebenzayo uqhelekile, ubukhulu beyunithi, ngcono ukusebenza kokuqina.Oko kukuthi, i-viscosity ephezulu idinga inani elikhulu lamanzi, kwaye izinga lokugcinwa kwamanzi alitshintshi kakhulu.
3. Iinkampani ezininzi zisebenzisa i-ratios edityanisiweyo, oko kukuthi, i-mortars eyahlukeneyo kunye ne-cellulose ether specifications zihlukile, kodwa kwiifektri ezincinci, ziya kwandisa iindleko.Iifektri ezininzi ezincinci zisebenzisa kuphela ifayibha yeplastiki yefayibha ukuze isetyenziswe ngokubanzi, oko kukuthi, umthamo wahlukile.!Ngokubanzi, iiyunithi ze-100,000 zezona zisetyenziswa kakhulu.
4. Ngokuqhelekileyo i-200,000 viscosity isetyenziselwa udaka lwe-bonding, kwaye i-100,000 isetyenziselwa ukuzilinganisa, i-100,000 yokulinganisa, kunye ne-80,000 yokutyabeka.Ngokuqinisekileyo, ubukhulu becala buchongwa ngumgangatho wokugcinwa kwamanzi.Asicebisi abathengi ukuba basebenzise i-viscosity ephezulu.Ngokomzekelo, kwiiyunithi ezingama-200,000, ukuphakama kwe-viscosity ye-cellulose ether, ingazinzile, kwaye kukho iimveliso zomgunyathi.Abanye abathengi baxela ukuba imveliso yokwenyani ye-20W incangathi kakhulu kwaye ulwakhiwo alulunganga kakhulu.
5. Ukugcinwa kwamanzi kwe-cellulose ether esetyenziswe kwi-mortar kuhluke kukugcinwa kwamanzi kwe-cellulose ether kuvavanyo.Nokuba ukugcinwa kwamanzi kwi-ether cellulose ngokwayo kulungile, oko akuthethi ukuba umphumo kudaka uqinisekile Kulungile, kumiselwa ngokukodwa ngokusebenza kwezongezo eziseleyo kwifomula, ubungakanani bokudibanisa, kunye nesiphumo sokuxuba. isixhobo sodaka olomileyo lomgubo.Kungcono ukuyisebenzisa eludongeni ukuze ubone umphumo.Le yinyaniso!
