Sezvo indasitiri yekugadzira pasi rose ichivavarira kushanda zvakanaka, kushandisa mari zviri nani, uye kugadzirisa zvinhu zvisina njodzi, imwe nzira huru yemakemikari iri kuchinja chinyararire mamiriro eindasitiri yepolyurethane.Dimethylthioterephthalic anhydride, yakapfupikiswa seDMTDA (nhamba yeCAS: 106264-79-3), semushonga wekugadzirisa mvura, iri kupa vagadziri vekuSoutheast Asia neNorth America imwe nzira yakanaka inopfuura zvinhu zvechinyakare pakushanda kwayo.

I. Kutsanangura Patsva Maitiro Ekushanda: Mabhenefiti Akakosha eDMTDA

DMTDA haisi kungotsiva chete; imhinduro inovandudzwa nekushanda. Kana ichienzaniswa neMOCA, DMTDA yakawana hunhu hwakakwana muchimiro chemuviri, nyore kushanda, uye kushanda kwekupedzisira kwechigadzirwa.

Magadzirirwo Akakosha Ehunyanzvi:

Zita rechigadzirwa: Dimethyl Thio-Toluene Diamine (DMTDA)
Nhamba yeCAS:106264-79-3
Fomura reMamorekuru:C9H14N2S2
Chitarisiko:Mvura Yero Yakachenuruka Inoonekera
Kuchena:≥95% (Zviri muAmine Zvose)
Basa:Chinotambanudza Chain / Mumiriri Anorapa / Crosslinker

Maumbirwo emakemikoro eDMTDA anoibvumira kushanda se crosslinker inoshanda, ichipa hunhu hwakanaka hwemakemikari kune chigadzirwa chekupedzisira chepolymer. Hunhu hwayo hwemvura hunobvisa kudiwa kwekudziya kana kunyunguduka usati washandisa, chinhu chinowanzodiwa kune zvinhu zvakasimba zvinogadzirisa kupisa senge MOCA, nokudaro zvichichengetedza simba uye zvichivandudza kuchengetedzeka kwebasa.

II. Sei Uchifanira Kusarudza DMTDA? Kuchinja kubva kuMOCA

Kushanda kuri nyore, kushanda zvakanaka kwakapetwa kaviri

Mvura patembiricha yemumba: DMTDA inoonekwa semvura yero yakachenuruka ine viscous patembiricha yemumba, zvichibvisa kudiwa kwekunyunguduka kwakaoma seMOCA. Izvi hazvingochengetedze simba nemidziyo chete asiwo zvinorerutsa maitiro ekugadzira, zvichiwedzera kushanda zvakanaka kwekugadzira.

Kusviba kwakaderera, kuri nyore kusanganisa: Kusviba kwaro kwakaderera kunoita kuti risanganiswe nekukurumidza uye zvakafanana ne prepolymer, kunyanya zvakakodzera maitiro epamusoro akadai sekuumbwa kwe injection injection uye kupfapfaidza polyurea elastomers inoda kushanda zvakanaka pakusanganisa.

Kuchengetedza mari kwakanaka, mukana wekushandisa mari yakawanda

Muyero wakaderera: Kemikari yakaenzana neDMTDA yakaderera pane yeMOCA, zvichibvumira kudzikiswa kweinenge 20% mukushandiswa kwezvinhu mumabasa chaiwo. Izvi zvinoreva kuwana kushanda kwakafanana kana kuti kuri nani uku uchideredza zvakananga mitengo yezvinhu zvisina kugadzirwa.

Mutengo wakagadzikana: Nekuda kwemaitiro ekugadzira akakura uye mhedzisiro yakakura, iyomutengo weDMTDAinoramba yakagadzikana, ichipa vimbiso yakavimbika yekudzora mutengo kwenguva refu kumabhizinesi.

Hunhu hwakavandudzwa: Hunhu hwepamusoro-soro: Polyurethane elastomer yakanatswa neDMTDA inopfuura MOCA system muzviratidzo zvikuru zvakaita sekutsungirira, kuramba kupera, uye kuramba kutsemuka. Izvi zvinoita kuti chigadzirwa chekupedzisira chigare kwenguva refu uye chikwanise kumira mumamiriro ezvinhu akaomarara.

Inoshanda zvakanyanya: Kubva pamaroller ekudhinda anoshanda zvakanyanya, zvikamu zvemotokari, kusvika pakuputira kusingatsvi, zvinhu zvesimbi zvinodzivirira ngura, mamiriro ekushandisa eDMTDA ari kuramba achikura, zvichipa simba guru rekuvandudza zvigadzirwa mumaindasitiri akasiyana-siyana.

Yakachengeteka uye ine hushamwari kune zvakatipoteredza, ichitevedzera mafambiro epasi rose

Chepfu shoma, yakachengeteka: Chepfu yeDMTDAyakaderera zvikuru pane yeMOCA, uye haina njodzi dzinokonzerwa nekenza kana mutagenic, zvichivandudza zvakanyanya nzvimbo yekugadzira uye kuona hutano hwevashandi, zvichiita kuti mabhizinesi akwanise kutevedzera zviri nyore mitemo yakasimba yehutano nekuchengetedzeka kwebasa.

III. Maitiro asingakuvadzi nharaunda

Maitiro ayo ekugadzira anoshandisa nzira ye "neutral distillation" isingadhuri uye isingakuvadzi nharaunda, ichitevedzera maitiro epasi rose ekugadzira zvinhu zvakasvibira.

Kubatanidzwa Zvakadzama muSoutheast Asia neNorth America: Kubata Musika Kukuru

Kunyangwe matanho ebudiriro yemisika yeSoutheast Asia neNorth America akasiyana, ese ari maviri ane zvinodiwa nekukurumidza zvemhinduro dzezvinhu zvinoshanda zvakanyanya uye zvinobudirira zvakanyanya.

Musika wekuSoutheast Asia: Kukura kwezvivakwa nekugadzira zvinhu

Mafungu ekuvaka ane ruvara rwegirini: Nekukurumidza kwekukura kwemaguta munyika dzeSoutheast Asia, kudiwa kwezvinhu zvekuvaka zvine hunyanzaro kwakawedzera. Kushandiswa kweDMTDA mumachira asingatsvi uye munzvimbo dzesimbi dzinodzivirira ngura kunosangana zvakakwana nemazinga epamusoro ekuchengetedza zvivakwa uye kugara kwenguva refu kunodiwa nemusika uyu.

IV. Kuvandudzwa kwekugadzirwa kwezvinhu

Senzvimbo yakakosha yekutengeserana kwepasi rose mukugadzirwa kwezvinhu, maindasitiri emotokari, machira, uye mapepa ekuSoutheast Asia ari kukura nekukurumidza. Kushandiswa kweDMTDA muminda yekugadzira zvinhu yepamusoro-soro senge zvikamu zvemotokari uye maroller ekudhinda kunogona kubatsira mabhizinesi emuno kusimudzira kukwikwidzana kwezvigadzirwa uye kutora cheni yemutengo wepamusoro-soro.

Musika wekuNorth America: Unyanzvi hwetekinoroji uye kugadzira kwepamusoro-soro

Chinosimudzira mashandiro epamusoro: Musika wekuNorth America unotungamira mune matekinoroji epamusoro akadai sekuumba majekiseni ekuita reaction uye kupfapfaidza polyurea elastomers. Semushonga wakanaka wekuporesa mvura,DMTDAinogona kushandisa zvizere mabhenefiti emaitiro aya uye kukurudzira hunyanzvi hwetekinoroji munzvimbo dzakadai sekugadzirisa mwenje yemotokari uye machira ekudzivirira anoshanda zvakanyanya.
