Mirayiridzo:

1. Tetrahydrofuran, iyo yakasvibirira yespandex synthesis, inogona kuve yega polycondensated (kuvhura mhete uyezve polymerization inotangwa nekate) kune poly (tetramethylene ether glycol) (PTMEG), inozivikanwawo se tetrahydrofuran polyether. PTMEG uye toluene diisocyanate (TDI) yakashandiswa kugadzira yakakosha rabha nekupfeka kuramba, mafuta kuramba, yakanaka yakaderera tembiricha kuita uye yakasimba simba, uye block polyether polyester elastic zvinhu zvakagadzirwa ne dimethyl terephthalate uye 1,4-butanediol. PTMEG ine mamorekuru uremu hwe2000 uye p-methylene bis (4-phenyl) diisocyanate (MDI) anoshandiswa seyakagadzirwa zvigadzirwa zve polyurethane elastic fiber (spandex fiber), yakakosha rabha uye zvimwe zvakakosha zvekupfeka. Iko kushandiswa kukuru kweTF kuburitsa PTMEG. Zvinoenderana neyakaomarara manhamba, anopfuura makumi masere muzana eTHF munyika inoshandiswa kuburitsa PTMEG, uye PTMEG inonyanya kushandiswa kugadzira elastic spandex fiber. 2.Tetrahydrofuran(THF) yakajairika yakanakisa solvent, kunyanya inokodzera kuparara kwePV, polyvinylidene chloride uye butylamine. Inoshandiswa zvakanyanya senge solvent yekumhara kwepasirese, anticorrosive coating, yekudhinda inki, tepi uye kupfeka kwefirimu. Inogona kudzora ukobvu uye kupenya kwealuminium layer kana ichishandiswa mune isina magetsi simbi yekugezera yekugezera. Tepi yekupenda, PVC pamusoro pekuputira, kuchenesa PVC reactor, kubvisa PVC firimu, cellophane kupfeka, epurasitiki yekudhinda inki, thermoplastic polyurethane bemhapemha, inonamira solvent, inoshandiswa zvakanyanya mukumhara kwepamusoro, yekudzivirira yekudzivirira, inki, yekumisikidza mumiriri uye yekugadzira yeganda pamusoro yekurapa mumiririri.

3. Inoshandiswa sezvinhu zvakasvibirira zve organic synthesis senge mishonga yemishonga. Mune indasitiri yemishonga, inoshandiswa kugadzira kebiqing, rifamycin, progesterone uye mamwe mahormone zvinodhaka. Inogona kushandiswa sekunhuhwirira mumiririri (kuzivikanwa kwekuwedzera) mupeturu gasi uye chikuru solvent mumishonga indasitiri.

4. kudiwa kwePTMEG muChina kuri kuwedzera zuva nezuva, uye kudiwa kwe tetrahydrofuran kuri kuratidza zvakare kukurumidza kukura maitiro.

Chengetedzo yekuchengetedza: kazhinji, zvigadzirwa zvinowedzerwa nepolymerization inhibitor. Chengetera mune inotonhorera uye nemhepo yekuchengetera. Gara kure nemoto uye sosi inopisa. Iyo tembiricha yekuchengetera haifanire kupfuura 30 ℃. Iyo pasuru inofanirwa kuvharwa uye kwete kusangana nemhepo. Inofanirwa kuchengetwa yakaparadzaniswa neacididant, acid, alkali, nezvimwewo Kuputika kwemwenje uye nzvimbo dzekufefetedza dzinogamuchirwa. Izvo zvinorambidzwa kushandisa michina michina uye maturusi ari nyore kuburitsa sparks. Iyo nzvimbo yekuchengetera ichave yakagadzirirwa ne leakage emergency emergency michina uye yakakodzera yekuchengetedza zvinhu.
