Madhaka ekuzvimisa ari kuwedzera mukurumbira muindasitiri yekuvaka nekuda kwekureruka kwekushandisa, yakanakisa kuyerera zvivakwa, uye kugona kupa yakatsetseka, yakati sandara nzvimbo.Pakati pezvakasiyana-siyana zvinoshandiswa mukuzvimisa-leveling madhaka, hydroxypropyl methylcellulose (HPMC) inoita basa rakakosha mukudzora viscosity.
Idhaka inozvimisa ine mukurumbira muindasitiri yekuvaka nekugona kwayo kugadzira nzvimbo yakatsetseka, yakati sandara nekuedza kushoma.Zvishandiso izvi zvinopa mabhenefiti akakosha pamusoro pechinyakare nzira dzekuyera, senge nyore kushandisa, nekukurumidza kuomesa uye kuenderana neakasiyana ma substrates.Chinokosha pakuita kwe-self-leveling dhaka ndiyo chaiyo yekudzora rheological properties, kunyanya viscosity, iyo inobata zvakananga kuyerera uye kuenzana kwezvivakwa.
1.Basa reHPMC mukuzvimisa-leveling dhaka:
Hydroxypropylmethylcellulose (HPMC) is cellulose ether inowanzoshandiswa seyakakora uye rheology modifier mune zvekuvaka.Mumadhaka ekuzvimiririra, HPMC inoita mabasa akawanda, anosanganisira kuchengetedza mvura, kukwidziridzwa kushanda, uye viscosity control.Yakaderera viscosity HPMC inonyanya kukosha sezvo ichipa kuyerera kuri nani uye kuenzana uku ichichengetedza yakakwana kuchengetedza kwemvura uye michina zvinhu.
2. Kukosha kweyakaderera viscosity HPMC:
Kuwedzeredzwa kuyerera: Yakaderera viscosity HPMC inofambisa kuyerera kweanozvimisa madhaka, achiabvumira kupararira zvakaenzana pamusoro uye zvinobudirira kuzadza voids uye hurema.Izvi zvinoita kuti pave nekugadzikana, kupedzisa yunifomu, kuderedza kudiwa kwekuwedzera kugadzirira kwepamusoro.
Kuvandudzwa kwekushanda: Madhaka ekuzvimisikidza ane yakaderera-viscosity HPMC ari nyore kusanganisa, kupomba uye kudurura, kuvandudza kushanda uye kuderedza basa rezvinodiwa.Makondirakiti anogona kuwana hukuru hukuru uye kugona panguva yekunyorera maitiro.
Inoderedza njodzi yekusarura: Yakakwira viscosity additives inogona kukonzera matambudziko ekuparadzanisa, ayo asina kuenzana kugadzirisa akaunganidzwa mumusanganiswa wevhu.Low viscosity HPMC inobatsira kudzivirira kupatsanurwa, kuve nechokwadi chekufanana uye kuenderana mune yekupedzisira chigadzirwa.
Deredza kuvharirwa kwemhepo: Viscosity yakawandisa inogona kuteya mabhuru emhepo mumatope matrix, zvichikanganisa kusimba uye kusimba kwechinhu.Nekushandisa yakaderera viscosity HPMC, njodzi yekupinda mhepo inodzikiswa, zvichikonzera denser, yakasimba nzvimbo.
Kuenderana neKupomba Equipment: Madhaka ekuzvimisikidza anowanzoda kupomba kwekushandisa kwakakura.Iyo yakaderera viscosity HPMC fomula inoenderana nekupomba michina yekushanda, inoenderera kuburitsa pasina kuvhara.
3. Zvinhu zvinokanganisa viscosity:
Zvinhu zvakati wandei zvinogona kukanganisa viscosity yekuzvimisa dhaka, kusanganisira:
Mhando yepolymer uye uremu hwemamorekuru: Rudzi uye huremu hwemamorekuru eHPMC ane chekuita kwakakura pane viscosity.Lower molecular uremu mapolymers anowanzo ratidza yakaderera viscosity, nepo yakakwirira molecular uremu mapolymers anogona kukonzera kuwedzera viscosity.
Polymer yemukati: Iyo yekumisikidzwa kweHPMC mumatope ekugadzira inokanganisa viscosity, ine yakanyanya kuwanda inowanzo konzera yakakwira viscosity.
Saizi yechikamu uye kugovera: Saizi yechikamu uye kugovera kwezvakaomesesa zvikamu (semu simende uye aggregate) zvinopesvedzera rheological maitiro ezvigadziriso zvedhaka.Finer particles anogona kubatsira kuwedzera viscosity nekuda kwekuwedzera kwepamusoro nzvimbo uye interparticle kupindirana.
Reshiyo yemvura kune binder: Hyero yemvura kune binder zvinhu (kusanganisira HPMC) inokanganisa zvakananga kuyerera uye viscosity yedhaka rinozvimisa.Kugadzirisa mvura kune binder reshiyo inobvumira kunyatso kudzora viscosity uye kuyerera maitiro.
Kusanganisa Maitiro: Yakakodzera kusanganisa maitiro, kusanganisira kusanganisa nguva nekumhanya, inogona kukanganisa kupararira kweHPMC mumatope matrix, nekudaro kukanganisa viscosity uye kuita kwese.
4. Wana yakaderera viscosity HPMC kuumbwa:
Kuti uwane yakaderera viscosity HPMC maumbirwo ezvigadziriso zvedhaka, akati wandei maitiro anogona kushandiswa:
Kusarudza iyo Yakakodzera HPMC Giredhi: Vagadziri vanogona kusarudza HPMC mamakisi ane yakaderera mamorekuru uremu uye akagadziridzwa viscosity profiles kuti asangane nezvinodiwa zvekushandisa.
Recipe Optimization: Kunyatsogadzirisa zvinongedzo zveiyo-yega-yepamusoro dhaka, kusanganisira iyo mhando uye chiyero chezvishongedzo, zvinogona kubatsira kuzadzisa inodiwa viscosity renji.
Kuwedzerwa kwevanoparadzira: Kuwedzerwa kwevanoparadzira kana defoamers kunogona kuvandudza kupararira kweHPMC mumusanganiswa wematope, kuderedza viscosity uye kuderedza kupindira kwemhepo.
Kushandiswa kwepamusoro shear musanganiswa: Yakakwira shear yekusanganisa michina inogona kusimudzira kupararira kweyunifomu yeHPMC uye zvimwe zvinowedzera, kuwedzera fluidity, uye kuderedza viscosity.
Kudzora tembiricha: Tembiricha inokanganisa rheological zvimiro zvekuzvimisa-leveling dhaka.Kudzora tembiricha panguva yekusanganisa uye kushandisa kunobatsira kuwana inodiwa viscosity uye kuyerera maitiro.
5. Mafambiro uye tarisiro yeramangwana:
Iko kugadziridzwa kweyakaderera-viscosity HPMC maumbirwo ezvigadziriso zvedhaka zvinotarisirwa kuenderera mberi sezvo vagadziri vanoyedza kuvandudza mashandiro, kusimba uye hushamwari hwemushandisi.Mafambiro emangwana anogona kusanganisira:
Kubatanidzwa kwezvinhu zvinogoneka: Kukura kwekutarisa kwekusimba kunogona kufambisa kutorwa kwebio-based kana kudzokororwa zvinhu sedzimwe nzira dzechinyakare zvinowedzera, kusanganisira HPMC.
Advanced Rheology Modifiers: Kuenderera mberi nekutsvaga mune nyowani rheology modhifita uye zvekuwedzera zvinogona kutungamira mukuvandudzwa kwemamwe maumbirwo anoshanda kuti awane yakaderera viscosity uye inowedzerwa kuyerera zvivakwa.
Digital modelling uye simulation: Kufambira mberi mudhijitari modhi uye simulation tekinoroji inogona kufambisa optimization yekuzvimisikidza yedhaka maumbirwo, zvichibvumira kunyatso kudzora kwe viscosity uye kuita.
Zvigadziriso zvakagadziridzwa zvemashandisirwo chaiwo: Vagadziri vanogona kupa zvigadziriso zvakagadziridzwa kune chaiwo maapplication zvinodiwa, senge dhaka rekukurumidza-kugadzika mapurojekiti anobata nguva kana guruva rakaderera remukati menzvimbo dzemukati.
Yakaderera viscosity HPMC inoita basa rakakosha mukuita kweanozvigadzirisa madhaka, kuwedzera kuyerera, kushanda uye kuenderana.Nekunyatso kudzora viscosity, vagadziri vanogona kugadzira madhaka ane akatsetseka, akati sandara nzvimbo ine simba shoma uye kugona kwakanyanya.Sezvo indasitiri yekuvaka iri kuramba ichishanduka, kuvandudzwa kweyakaderera-viscosity HPMC maumbirwo anoramba akakosha kusangana nekukura kuri kudiwa kwemhando yepamusoro, mushandisi-inoshamwaridzika nhanho mhinduro.
