Cellulose ether ni uruganda kama rufite imikorere myiza, rukoreshwa cyane mubijyanye nibikoresho byubaka, cyane cyane mugutegura urukuta rwimbere hamwe nimbere ninyuma. Ntishobora gusa kunoza imikorere yubwubatsi bwa putty, ariko kandi irashobora kunoza igihe kirekire nimbaraga za putty nyuma yo kubisaba.
1. Incamake ya selile ether
Cellulose ether nicyiciro cyamazi ashonga cyangwa atandukanya amazi ya polymer yakozwe noguhindura imiti ishingiye kuri selile naturel. Ethers isanzwe ya selile irimo hydroxypropyl methylcellulose (HPMC), hydroxyethyl selulose (HEC), hydroxypropyl selulose (HPC), nibindi. ibikoresho.
2. Uruhare rwa selile ether muri putty
Kunoza imikorere yubwubatsi bwa putty
Cellulose ether itezimbere imiterere ya rheologiya ya putty, kugirango imikorere nogutondekanya imitungo ya putty irashobora kunozwa, byoroshye kuyikoresha no kurwego. Cyane cyane mubwubatsi bunini, imitungo yibyibushye ya selile irashobora gutuma hashyirwa neza kurukuta, kugabanya kugabanuka, no kwemeza ireme ryubwubatsi.
Kunoza gufata neza amazi
Igice cya putty gikeneye kugumana imiterere itose mugihe cyubwubatsi kugirango harebwe uburinganire no guhuza inzira yo gukama nyuma. Molekile ya selulose irashobora gukurura amazi menshi hanyuma igakora umuyoboro wa molekile wamazi muri putty, bikadindiza umuvuduko wamazi wamazi meza, bityo bigatuma amazi agumana neza. Uku kubika amazi bituma putty idakunda kumeneka cyangwa ifu iyo yubatswe mubushyuhe bwinshi cyangwa ahantu humye, byongerera igihe cyo gufungura no kwemeza ubuziranenge bwurwego.
Kongera imbaraga zubucuti
Kongera ibiri muri selulose ether birashobora kunoza ifatizo rya putty kandi ikemeza ko putty ifatanye neza hejuru yubuso. Iyo putty ishyizwe mubikorwa, selile ether ntishobora gusa kongera ubukana bwa putty, ariko kandi itanga urwego runaka rwo gufatira mugihe cyo kumisha kugirango irinde igishishwa kugwa cyangwa kugwa. Ibi ni ingenzi cyane kubuso bworoshye kandi budashiramo kuko selile ether itanga ubundi buryo bwo gufatira hamwe.
Igenzura umuvuduko wumye
Ether ya selile irashobora guhindura umuvuduko wumye wa putty kugirango igishishwa gishobora gukama neza, bityo bikarinda neza guturika biterwa no gutakaza amazi byihuse hejuru. Kubaka kubaka ibice byinshi, umuvuduko ukwiye wo gukama ni ngombwa cyane, bifasha kwemeza guhuza hagati yingaruka n'ingaruka rusange.
Kunoza imikorere irwanya kugabanuka
Mu rukuta ruhagaze cyangwa mu gisenge, putty yibasirwa ningufu zikomeye kandi ifite ibibazo byo kugabanuka no kugabanuka. Ingaruka yibyibushye ya selulose ether irashobora kunoza neza ububobere nubwitonzi bwa putty, ikabuza ibikoresho kunyerera bitewe nuburemere, kandi ikemeza ko igabanywa rimwe.
3. Ubwoko bwibanze no guhitamo selile ya selile
Ubwoko butandukanye bwa selile ethers ifite ingaruka zitandukanye muri putty, kandi ni ngombwa cyane guhitamo ubwoko bwiza bwa selile. Ibikurikira nibintu byinshi bikunze gukoreshwa na selile ya selile nibiranga:
Hydroxypropyl methylcellulose (HPMC): Ifite umubyimba mwiza, kubika amazi hamwe no gukora firime kandi ikoreshwa cyane mukubaka putty. HPMC irashobora kunoza cyane imyubakire nogukora firime ya putty, gukora putty yoroshye mugihe ushyizwe mubikorwa, no kunoza gufatana no korohereza putty.
Hydroxyethyl selulose (HEC): Ikoreshwa cyane cyane muri sisitemu ishingiye ku mazi, ifite ubushobozi bwo kubyimba no kugenzura indwara ya rheologiya, kandi ikoreshwa kenshi mu rukuta rw'imbere rushyizweho n'amazi. HEC ifite ingaruka nziza zo gutera imbere kurwego rwa putty, ariko kubika amazi kwayo kurutwa na HPMC.
Hydroxypropyl selulose (HPC): HPC ifite ubukonje bwinshi kandi butajegajega, kandi irakwiriye mubihe bisabwa cyane kugirango birwanye. Ongeraho umubare ukwiye wa HPC kuri putty birashobora kunoza cyane imikorere yo kurwanya kugabanuka nimbaraga za putty.
4. Ibyiza byo gukoresha hamwe nisoko ryisoko rya selile
Ibyiza byo gukoresha selile ya ether muri putty ni ngombwa, ahanini bigaragarira mubice bikurikira:
Kuzigama ibiciro: Ethers ya selile irashobora kunoza neza imikorere yakazi ya putty, kugabanya umubare wimirimo, bityo bikagabanya ibiciro byakazi nakazi.
Kurengera ibidukikije: Ethers ya selile ni ibikoresho karemano bikozwe mumitungo ishobora kuvugururwa, hamwe no kurengera ibidukikije neza, bidafite uburozi kumubiri wumuntu, kandi bifasha guhaza ibikenerwa byubwubatsi bugezweho bwo kurengera ibidukikije.
Kumenyera ikirere gitandukanye: Kubika amazi no kurwanya ibice bya selile ya selile bituma bikenerwa mu iyubakwa mu bihe bitandukanye by’ikirere, byujuje ibyifuzo by’ubwubatsi butandukanye nko mu majyaruguru yumye no mu majyepfo.
Icyerekezo cyiza cyamasoko: Hamwe niterambere ryinyubako zicyatsi hamwe nubwiyongere bwibikoresho byubaka bikora neza, isoko ryisoko rya ether ya selile nkuko inyongeramusaruro ziyongereye uko umwaka utashye. Cyane cyane mu nganda zishushanya, ibisabwa kugirango uburinganire bwurukuta nubwiza bwubuso bwaratejwe imbere, byaguye umwanya witerambere ryibicuruzwa byoroshye. Cellulose ether nkumuhinduzi azagira ibyifuzo byinshi byo gusaba.
5. Kwirinda selulose ether mugushira mubikorwa
Nubwo selulose ether ifite ibyiza byinshi muri putty, ingingo zikurikira zigomba kwitonderwa mubikorwa nyirizina byo gusaba:
Kugenzura ibipimo: Kwiyongera cyane kwa selile ether bizatera ubukonje bukabije bwa putty kandi bigira ingaruka kurwego rwubwubatsi. Kubwibyo, ingano ya selulose ether yongewe muri formula ya putty igomba kugenzurwa neza kugirango harebwe imikorere myiza yubwubatsi.
Ikwirakwizwa rimwe: Ikwirakwizwa rya selile ether muri putty bizagira ingaruka ku ngaruka zabyo. Kugirango wirinde igiteranyo cya selile ya selile, ni ngombwa gufata uburyo bukwiye bwo gukurura mugihe utegura putty kugirango urebe neza ko ikwirakwijwe mugice cyamazi.
Guhuza nibindi byongeweho: Ifumbire mvaruganda isanzwe irimo izindi nyongeramusaruro, nka pisitori ya redxersible latex, yuzuza, nibindi. Guhuza kwa selile ya ether hamwe nibindi byongeweho bizagira ingaruka kuburyo butaziguye kumikorere ya putty, bityo imikoranire hagati yibintu bitandukanye igomba gutekerezwa byuzuye mugihe cyo gushushanya amata.
Ikoreshwa rya selile ya ether muri salit ya putty na putty ntabwo itezimbere gusa kubaka no gukoresha ingaruka za putty, ahubwo inongerera igihe cyumurimo wa putty kandi igabanya ibibazo byubwiza biterwa nubwubatsi budakwiye. Hamwe nogukomeza kwaguka kwicyatsi kibisi nibikoresho byo gushushanya isoko, selile ether, nkibidukikije byangiza ibidukikije kandi byongera inyubako, ifite ibyifuzo byinshi. Mugushushanya kwa formulaire, guhitamo neza no gukoresha ether ya selile irashobora gutanga uburinganire bwiza kandi burambye kubwinkuta zubaka, bityo bikuzuza ibihe bitandukanye byikirere nibisabwa mubwubatsi, kandi bigatanga ingwate zikomeye ziterambere ryiza ryiterambere ryinyubako zigezweho.
