Mukugadzirwa kwekunamatira, cellulose ether, sechinhu chinokosha chekuwedzera, ine zvakasiyana-siyana zvakasiyana-siyana uye inogona kuvandudza zvakanyanya kushanda kwekunamatira. Cellulose ether compounds inotorwa kubva kune yakasikwa cellulose uye inogadzirwa nekemikari yakagadziriswa, yakadai sehydroxypropyl methylcellulose (HPMC), methylcellulose (MC), carboxymethylcellulose (CMC), nezvimwewo. formulations.
1. Zvinhu zvakakosha zve cellulose ethers
Cellulose ether inoumbwa kubva kumakemikari ekugadzirisa echisikigo cellulose uye isiri-ionic polymer compound. Zvimiro zvayo zvikuru zvinosanganisira zvinotevera
Solubility: Cellulose ether inogona kunyungudutswa mumvura inotonhora kana inopisa kuti iite yakagadzikana colloidal solution. Kunyungudika kwayo kunoenderana nerudzi uye chiyero chekutsiviwa kwezvinotsiva, uye kunyungudika kwayo kunogona kugadziriswa nekudzora chimiro che cellulose ether.
Kukora: Cellulose ethers ine yakanaka thickening mhedzisiro mumvura uye inogona kupa yakakosha viscosity kunatsiridza pane yakaderera concentration. Izvi zvinoibvumira kuti itambe viscosity inodzora basa mukunamira maumbirwo.
Mafirimu ekugadzira zvinhu: Cellulose ether inogona kuumba firimu rakasimba, rakajeka mushure mekuoma. Ichi chimiro chakanyatsokodzera kushandiswa mumunda wekunamatira uye chinobatsira mukuumbwa uye kurapa kwekupedzisira kweiyo adhesive layer.
Biodegradability: Cellulose ether inotorwa kubva kuzvinhu zvakasikwa, ine biocompatibility yakanaka uye kuora, uye haizokonzeri kusvibiswa kusingaperi kune zvakatipoteredza.
2. Iyo nzira yekuita kwe cellulose ether mune adhesives
Cellulose ethers inotamba mabasa akawanda mukugadzira zvinonamira, zvinosanganisira makobvu, zvinosimbisa, zvinogadzira firimu, uye rheology modhifita. Iyo huru nzira yekuita inogona kupfupikiswa sezvizvi:
Kukobvura nekumisa mhedzisiro: Cellulose ether mune zvinonamira zvinogona kuwedzera zvakanyanya viscosity yeformula uye kugadzirisa anonamira ekunamira zvimiro uye sag kuramba. Kune zvinonamira zvine zvimedu zvakasimba, cellulose ether inogona kugovera zvakaenzana zvimedu zvakasimba mumushonga, kudzivirira kubva pakugadzirisa, uye kubatsira kuvandudza kumira uye kuchengetedza kugadzikana kwekunamatira.
Vandudza zvekupfeka uye zvivakwa zvekuvaka: Nekugadzirisa iyo rheology yekunamira, cellulose ethers inogona kuita kuti inonamira ive yunifomu uye yakatsetseka panguva yekupfekedza, kuderedza dambudziko remvura panguva yekuvaka. Inogona kudzivirira zvinonamira kubva pakudonha kana ikaiswa panzvimbo yakatwasuka, ichiita kuti ive yakanyatsokodzera vertical coating.
Firimu-kuumba uye kugadzirisa kugadzirisa: Iyo firimu-inogadzira pfuma ye cellulose ether mune adhesive inoita kuti iite inoenderera inonamira firimu panguva yekuomeswa, nekudaro ichiwedzera kusimba kwekubatanidza. Iyo firimu inoumbwa nayo inogona kuita basa rekudzivirira, kudzivirira mwando mumucheka wekunamira kubva pakubuda nekukurumidza, uye kubatsira chinonamira kusimba zvakaenzana munzvimbo dzakasiyana.
Kuvandudza kudzivirira kwemvura uye kuomesa chando: Modified cellulose ether ine yakanaka yekudzivirira mvura uye nechando-thaw cycle kuramba, kunyanya mumanamira ekuvaka. Inogonesa chinonamira kuchengetedza kusimba kwechisungo munzvimbo dzine hunyoro, kudzivirira kupfava uye kupepeta kweiyo adhesive layer, uye kuchengetedza yakanaka elasticity uye kunamatira pasi pemamiriro ekushisa akadzika.
3. Zvakanakira zve cellulose ethers mune adhesive formulations
Kuwedzera simba rekubatanidza: Iyo firimu-inogadzira zvinhu zve cellulose ether inogona kuwedzera kusimba kwekubatanidza kweanonamatira, kunyanya kune anonamatira mumunda wekuvaka, senge matairi adhesives, plastering adhesives, nezvimwe. adhesive layer. Knot performance uye kusimba.
Optimize rheology uye kushanda: Kugona kwe cellulose ether kudzora rheology yekunamira kunogona kuvandudza zvivakwa zvekupfeka panguva yekushanda, kudzivirira kudonha, uye kunatsiridza mashandiro ekuvaka. Pamusoro pezvo, kugadzikana kwayo mukupisa kwepamusoro kana kunyorova kwenzvimbo kunoita kuti ive yakakodzera kune dzakasiyana siyana dzakaoma mamiriro ekuvaka.
Yakawedzerwa nguva yekuvhura: Munguva yekuvaka, cellulose ether inogona kunonoka kuomeswa nguva yekunamatira, ichipa vashandisi nguva yakawanda yekugadzirisa uye kugadzirisa, iyo inonyanya kukodzera kune yakakura-nzvimbo yekuvaka zvinodiwa. Ichi chivakwa chakanyanya kukosha mune anonamira maumbirwo anoda kunyatsoshanda, senge zvinonamira zvekuvaka uye zvinonamira pamadziro.
Zvivakwa zvine hushamwari kwezvakatipoteredza: Cellulose ether inongobva kuzvinhu zvakasikwa uye ine biodegradability yakanaka. Kuenzaniswa neyechinyakare synthetic polymer additives, inonyanya kushamwaridzana nharaunda uye haizokonzerese kusvibiswa kwenguva refu kune nharaunda. Izvo zvinoenderana nezvino kusimudzira maitiro egirinhi uye kuchengetedzwa kwezvakatipoteredza.
Kuvandudza kupikisa kwemamiriro ekunze: Cellulose ether inogona kuvandudza kuchembera kwekunamatira uye kudzivirira kushanda kweadhesive layer kubva pakuderera pasi penguva refu ye ultraviolet radiation kana yakaoma mamiriro ekunze. Iyo antioxidant properties inobatsirawo kuwedzera hupenyu hwekunamatira.
4. Minda yekushandisa inoshanda
Cellulose ethers yakashandiswa zvakanyanya mumhando dzakasiyana dzezvigadzirwa zvekunamira, uye nzvimbo dzadzo dzekushandisa dzinosanganisira asi hadzina kugumira kune:
Zvisungo zvekuvaka: Mumunda wekuvaka, cellulose ethers inoshandiswa zvakanyanya mumatairi ekunamira, madhaka akaoma, mukati uye kunze kwemadziro emadziro madhiraivha uye zvimwe zvigadzirwa kuvandudza kuvaka kwavo, kudzivirira kwemvura uye kusimba kwekubatanidza.
Pepa uye kurongedza: Iyo firimu-inogadzira zvimiro uye yakanaka kunyungudika kwemvura ye cellulose ethers inovaita zvakanakira zvinongedzo mumapepa anonamira uye mabhuku anosunga glues.
Kugadziriswa kwehuni: Muzvinonamira zvehuni, kukobvu nekusunga zvivakwa zve cellulose ethers zvinobatsira kuvandudza hukama hwezvinhu zvakaita seplywood nefiberboard.
Kushongedzwa kwepamba: Mune zvinonamira zvekushongedza imba senge Wallpaper glue uye kapeti glue, kushandiswa kweselulosi ether kunoita kuti zvive nyore kupfeka uye ine yakanaka yekuvhura nguva uye firimu-kugadzira zvinhu.
Sechikamu chakakosha mukugadzirwa kwekunamira, cellulose ether ine mabasa akawanda akadai sekukora, kugadzira firimu, uye rheology kugadzirisa, uye inogona kuvandudza zvakanyanya kushanda kweinamira, kusimba kwekubatanidza, uye kusimba. Uye zvakare, yakanaka kuchengetedza kwezvakatipoteredza zvivakwa uye biocompatibility zvakare inoita kuti ive chinhu chakakosha chekuwedzera muindasitiri yekunamira mumamiriro ezvinhu ekutsvagisa kwazvino kwegirinhi uye kusimudzira kwakasimba.
