I. Nhanganyaya Pfupi yeChigadzirwa: Mushonga Unofashaira Unoshanda Zvakanyanya
Diethylene Glycol Monobutyl Ether, inowanzo pfupikiswa seDEGMBE kana BDG, iorganic solvent isina ruvara, inoonekera uye ine hwema husina kujeka hwakaita sebutanol. Senhengo yakakosha yemhuri yeglycol ether, chimiro chayo chemamorekuru chine ether bonds uye hydroxyl groups, zvichiita kuti ive nehunhu hwakasiyana hwe physicochemical hunoita kuti ive "substantial solvent" yakanaka kwazvo inofashaira pakati nepakati kusvika pakakwirira, ine low-volatility.
Simba guru raDEGMBE riri mukunyungudika kwayo kwakanyanya uye kugona kwayo kubatanidza. Inoratidza kusimba kwakasimba kwezvinhu zvakasiyana-siyana zvepolar nezvisiri polar, zvakaita semaresini, mafuta, madhayi, uye cellulose. Chinonyanya kukosha ndechekuti DEGMBE inoshanda semushonga wekubatanidza, zvichiita kuti masisitimu ekutanga aisaenderana (semuenzaniso, mvura nemafuta, maresini eorganic nemvura) agadzire mhinduro dzakagadzikana, dzakafanana kana emulsions. Chinhu ichi chakakosha, pamwe chete nemwero wayo wepakati wekubuda kwemvura uye hunhu hwakanaka hwekuyera, ndiyo hwaro hwekushandiswa kwakawanda kweDEGMBE muminda inotevera:
●Indasitiri yeCoatings & Inks: Inoshandiswa sechinhu chinonyungudutsa uye chinobatanidza pendi dzinobva mumvura, pendi dzelatex, pendi dzekubika dzemuindasitiri, uye inki dzekudhinda, inovandudza kuenzanisa kwefirimu uye kupenya uku ichidzivirira firimu kutsemuka pakupisa kwakaderera.
●Vanochenesa & Vanobvisa Pendi: Chinhu chakakosha muvazhinji vanochenesa maindasitiri, vanobvisa mafuta, uye vanobvisa pendi, DEGMBE inonyungudutsa mafuta nemafirimu ependi ekare zvinobudirira.
●Kugadziriswa Kwemachira Nedehwe: Inoshanda semushonga wedhayi nezvimwe zvinobatsira, zvichiita kuti zvive nyore kupinda mukati meganda zvakaenzana.
●Makemikoro Emagetsi: Anoshanda muzvidzitiro zve photoresist uye mune mamwe ma electronic cleaning solutions.
●Mimwe Minda: Inoiswa mumishonga inouraya zvipembenene, mvura inoshandiswa musimbi, zvinonamira zvepolyurethane, nezvimwewo.
Saka, kunyange hazvo DEGMBE isingaumbi zvakananga zvinhu zvikuru zvakaita se bulk monomers, inoshanda se "industrial MSG" yakakosha - ichitamba basa risingatsivike mukusimudzira mashandiro ezvigadzirwa uye kugadzikana kwemaitiro mumaindasitiri mazhinji ari pasi.
II. Nhau Dzazvino: Musika Usina Kudiwa Kwakawanda Kwezvinhu Zvinodiwa Uye Mitengo Yakakwira
Munguva pfupi yapfuura, zvichikonzerwa nekugadziriswa kwecheni yemaindasitiri pasi rose uye kusagadzikana kwezvinhu zvakagadzirwa, musika weDEGMBE wave uine kushomeka kwezvigadzirwa uye mitengo yakakwira.
Kusagadzikana kweEthylene Oxide muzvinhu zvisina kugadzirwa kunopa rutsigiro rwakasimba
Zvinhu zvikuru zvekugadzira DEGMBE iethylene oxide (EO) ne n-butanol. Nekuda kwesimba rayo rekupisa uye kuputika, huwandu hwekutengeserana kwayo hwakaganhurirwa, nemitengo yakasiyana-siyana yematunhu uye kuchinja-chinja kwakawanda. Munguva pfupi yapfuura, musika weEO wemuno wakaramba uri padanho repamusoro remitengo, zvichikonzerwa nemafambiro e ethylene uye simba rayo rekupa-kuda, zvichigadzira rutsigiro rwakasimba rwemutengo weDEGMBE. Chero kuchinja-chinja mumusika we n-butanol kunotumirwawo zvakananga kumitengo yeDEGMBE.
Kuwanikwa Kwakasimba Kwakasimba
Kune rumwe rutivi, dzimwe nzvimbo huru dzekugadzira dzakambovharwa zvakarongwa kana kuti zvisina kurongwa kuti dzigadziriswe munguva yapfuura, zvichikanganisa kuwanikwa kwenzvimbo. Kune rumwe rutivi, zvinhu zvese zviri muindasitiri zvakaramba zviri padanho rakaderera. Izvi zvakaita kuti pave nekushomeka kwenzvimbo DEGMBE mumusika, nepo makambani ari kuramba achiratidza mafungiro avo.
Kudiwa Kwepasi Kwakasiyana
Sechikamu chikuru cheDEGMBE chekushandisa, kudiwa kweindasitiri yezvekuputira kwakabatana zvakanyanya nekubudirira kwezvivakwa nekuvaka zvivakwa. Parizvino, kudiwa kwezvekuputira zvekuvaka kuchiri kugadzikana, nepo kudiwa kwezvekuputira zvemaindasitiri (semuenzaniso, zvemotokari, zvemugungwa, uye zvemakontena) kuchipa simba kumusika weDEGMBE. Kudiwa kwezvishandiso zvechinyakare zvakaita sezvekuputira kuchiri kuenderera mberi. Kugamuchirwa kwevatengi veDEGMBE inodhura zvakanyanya kwave chinhu chinonyanya kutariswa mumitambo yemusika.
III. Mafambiro Eindasitiri: Kuvandudzwa Kwezvakatipoteredza uye Kuvandudzwa Kwakagadziriswa
Tichitarisa mberi, kukura kweindasitiri yeDEGMBE kuchave kwakabatana zvakanyanya nemitemo yezvakatipoteredza, kufambira mberi kwetekinoroji, uye shanduko mukudiwa kwemusika.
Kukurukurirana Kwekusimudzira Chigadzirwa uye Kutsiva Chinotungamirwa Nemirau Yezvakatipoteredza
Zvimwe zvinonyungudutsa glycol ether (kunyanya E-series, zvakaita se ethylene glycol methyl ether uye ethylene glycol ethyl ether) zvakaganhurirwa zvakanyanya nekuda kwekutya. Kunyangwe DEGMBE (yakarongwa pasi peP-series, kureva, propylene glycol ethers, asi dzimwe nguva inokurukurwa muzvikamu zvechinyakare) ine chepfu shoma uye mashandisirwo akawanda, maitiro epasi rose e "green chemistry" uye kuderedzwa kweVOC (Volatile Organic Compounds) emissions zvakaisa kumanikidzwa kuindasitiri yese yezvinyungudutsa. Izvi zvakakurudzira R&D yezvimwe zvinotsiva zvakatipoteredza (semuenzaniso, mamwe ma propylene glycol ethers) uye zvakaita kuti DEGMBE pachayo ikure yakanangana nekuchena kwakanyanya uye kudzikira kwemazinga ekusvibiswa.
Kuvandudzwa Kwemaindasitiri Kunosimudzira Kudiwa Kwemari
Kukurumidza kukura kwezvipfeko zvemaindasitiri zvepamusoro-soro (semuenzaniso, pendi dzemaindasitiri dzinobva mumvura, zvipfeko zvakasimba), inki dzinoshanda zvakanyanya, uye makemikari emagetsi zvakaisa zvinodiwa zvakanyanya pakuchena kwezvinonyungudutsa, kugadzikana, uye zvinhu zvakasara. Izvi zvinoda kuti vagadziri veDEGMBE vasimbise kudzora mhando uye vape zvigadzirwa zveDEGMBE zvakagadzirwa kana kuti zvepamusoro-soro zvinosangana nezvinodiwa zvekushandisa zvepamusoro-soro.
Shanduko muMaitiro Ekugadzira Mudunhu
Kugona kwekugadzira kweDEGMBE pasi rose kwakanyanya kuChina, North America, Western Europe, nedzimwe nzvimbo dzeAsia. Mumakore achangopfuura, kugona kwekugadzira kweChina uye simba rayo zvakaramba zvichikwira, zvichitsigirwa nekambani yemaindasitiri yakazara uye musika mukuru uri pasi. Mune ramangwana, kurongeka kwekugadzira kucharamba kuchiswedera pedyo nemisika mikuru yevatengi, nepo mitengo yezvakatipoteredza nekuchengetedza ichizova zvinhu zvikuru zvinokanganisa kukwikwidzana kwenzvimbo.
Kugadzirisa Maitiro uye Kubatanidzwa Kwemaindasitiri
Kuti vawedzere kukwikwidzana kwemitengo uye kugadzikana kwezvekuwanikwa kwezvinhu, vagadziri vanotungamira vanowanzo gadzirisa maitiro ekugadzira DEGMBE kuburikidza nekuvandudza tekinoroji, kuwedzera kushandiswa kwezvinhu zvakabikwa uye goho rezvigadzirwa. Panguva imwecheteyo, mabhizinesi ane kugona kwekugadzira ethylene oxide kana alcohols kwakabatana ane mukana wakasimba wekudzivirira njodzi mumakwikwi emusika.
Muchidimbu, semushonga unoshanda zvikuru, musika weDEGMBE wakabatana zvikuru nezvikamu zvekugadzira zvakaita semachira nekuchenesa—zvichishanda se "barometer" yekubudirira kwavo. Vakatarisana nematambudziko maviri ekumanikidzwa kwemitengo yezvinhu zvisina kugadzirwa uye mitemo yezvakatipoteredza, indasitiri yeDEGMBE iri kutsvaga mikana mitsva yekuvandudza nekuvandudza mhando yezvigadzirwa, kugadzirisa macheni ekupa, uye kugadzirisa kudiwa kwepamusoro-soro, ichiva nechokwadi chekuti "mushonga uyu unochinjika-chinjika" unoramba uchitamba basa rawo rinokosha muhurongwa hwemazuva ano hwemaindasitiri.
