Glycol Propylene - he aha te mea te reira? āhuatanga matū, te whakamahi o

Ko tētahi o te tino noa i roto i te Paku, kakara me te kai ngā ahumahi, me te te ao hangarau ko te taonga organic no ki waiwaihā. Ko tōna ingoa - propylene glycol. He aha te mea te reira? Whakaaroa nga āhuatanga, hanganga rāpoi me te whakamahi o tenei pūhui i roto i te tuhinga.

glycol Propylene - he aha te mea te reira?

i timata tenei iwi dialcohol ki te whakamahi i te taenga atu ano i kitea e ratou i roto i te mea ngā āhuatanga whai hua, me te nui roaa te reira. Waho e rere ke te reira iti i te waihā ranei nonireka, me te te mārama wai. Heoi, he teitei ake i te waihā, engari i raro i taua o te nonireka tona pokey. E ai ki tona te tāoke ko reira nui iho ki te hoa tata i roto i te raupapa huirua - ethylene glycol.

Ki te ethanediol - he paihana kaha, te glycol propylene - kahore. hāngai ana te whakamahi o tenei rauemi kei i runga i ona āhuatanga tinana, me te matū. Ki te whakaahua poto tatou i te rāngai matua i roto i nei i reira he propylene glycol, ka kia whakahuatia te tono i roto i te maha rāngai o te ōhanga.

1. ahumahi Chemical.
2. Rererangi me te pereoo hanga.
3. Oil me ahumahi hau.
4. Peita me te ahumahi wanihi.
5. Paku me te mea kakara ahumahi.
6. Production Food.
7. mara Hangarau o mahi.
8. Medicine.

Ko reira kitea e whakaaro tatou he taonga ko te tino matū rauemi raw me te ūnga nui mo te hanga noa, me te mahi o ngā hanganga. Ko te aha e te hanga o te hua kia tātai i roto i taranata ia tau. kawea ano ona ki tāwāhi me kawemai i waenganui i nga whenua e rua i roto i kaha. Tata nga mara o te mahi me te hanga pānga te whakamahi o te taonga pērā i propylene glycol. He aha te mea te reira? He aha te mea tona hanganga matū, tātai me ngā āhuatanga? Ka tirotiro atu matou.

Ko te tātai me te rāpoi ngota

He maha ngā rerekē o te tātai e e taea e koe te whakaatu kahore anake te hanganga kounga, me te ine o te rāpoi ngota, engari te tikanga o here ngota i reira, e ko, te hanganga o te mea.

1. Rāpoi ranei tëtehi. E ai ki tenei tātai taea te whakawakia i runga i te hanganga o te pūhui. ka puta Propylene glycol rite C ₃ H ₈ E _2. Otiia e kore e he lekooti taua hoatu te taea ki te matapae i te āhuatanga o te taonga, no te mea te tikanga o te unknown ngota.
2. Ko te tātai hanganga CONDENSED. I roto i tenei take, i te hanganga propylene kua te tātai taua, engari kia whai rua momo: 1,2 - propanediol CH ₂ OH-CHOH-CH _3, me 1,3-propanediol CH ₂ OH-CH ₂ -CH ₂ OH. Ko te tūranga o te rōpū mahi pānga te tauhohenga o te taonga. I waenganui ia ratou i te hanganga e rua - poinanaha.
   
3. Full tātai hanganga. E whakaatu ana te reira i here ia i roto i te rāpoi ngota, tae atu i te pūhui i waenganui i te waro me te hauwai. Ko te glycol propylene hononga katoa kotahi sigma-momo, pera ki te tohu i te tikanga ki tonu o te hanganga e kore e.

Ka rite ki te taonga propylene ohie - te wai i te mea he ranunga racemic o rua hanganga isomeric optical. Ko e tika ana ki te ngota waro hangarite i roto i te mekameka tenei. Na reira, kotahi tītaka te waka rererangi o te marama polarised ki te matau me te tahi atu ki maui. Heoi, nga āhuatanga o te taonga e rite ana te katoa he tata kahore pānga.

ngā āhuatanga ōkiko o te taonga

I roto i ngā o ngā tawhā tinana, kua nga āhuatanga e whai ake nei 100% propylene glycol.

1. wai taekore, matotoru, Kaore, kua he uara kiato toharite.
2. I te mangai, sweetish, motuhake kakara.
3. Ko reira he whakarewa pai mo nga māngai o tata akomanga katoa o matū.
4. he wairewa i roto i te wai, me te waipiro me te kino Sam propylene glycol - i roto i te benzene me Etere.
5. Ko te ira koropupū o - 45.5 ⁰ C i te pēhanga noa. piki auau ki te whakanui ake te pēhanga.
6. He he nui rawa o te hygroscopicity.
7. whakaaturia te reira i āheinga waikura iti.

Taua āhuatanga tinana, me te whakatau i nga mara matua o tono o te taonga. I muri propanediol taea ki te faaiti i te makuku rangi mahanga reo totoka, me te here i te reira, e tukupu ana te pāmahana o matū, marara te pūhui a tawhio noa. Na reira, kua whakamahia te reira i roto i te ahumahi kai.

āhuatanga matū

Mai i te tirohanga o te tauhohenga, 1,3-propylene glycol he poinanaha atu urupare. I tua atu, e taea ki te polymerize ia. I roto i te whānui, i reira e e taea ki te tomo i te waipiro dihydric e rave rahi tauhohe nui.

1. Hākawatanga. Ki te waikawa organic me inorganic tali te ki te hanga i ngā hākawa.
2. Na roto i te tauhohe ki te alkali homai glycolates, te mea ano e tupu i roto i te pāhekoheko ki te konganuku alkali.
3. Nehenehe o te maroketanga ki te hanganga o aldehydes, allylic waiwaihā dimetildioksanov me ētahi atu hua.
4. tauhohe Dehydrogenation arahi ki te hanganga o te acetol, aldehydes, waikawa.
5. tahi te hāora e te hanganga o ngā rāpoi ngota o te hauwaiwaro, propionaldehyde, waikawa lactic, formaldehyde me ētahi atu pūhui.

whakaaro te whakamahi o tenei taonga i roto i te ahumahi te haumaru mō te taiao. Oia mau, ka rite ki te hua o te rāpoi ngota pirau stepwise i hanga noa te wai, me te hauhā. Ko te tukanga ko e whai ake:

• propylene glycol;
• waikawa lactic;
• PVK (waikawa pyruvic) ;
• wai;
• hāorarua waro.

Kei te reira whakaaro e taea ki te whakamahi i tenei hononga mō ngā take rerekē: e rua hangarau me te kai, me te Paku.

pānga tāoke i runga i te tinana, me te

Propylene glycol - he aha te mea te reira i roto i ngā o te pānga i runga i te tinana tangata? Kua whakaaturia ngā maha me ngā e te pānga kino tika i runga i te kopa ora me okana, e kore e tenei pūhui i. e kore e meinga ritenga me te whero o te kiri, e kore e kohikohi i roto i te ate, me whatukuhu, rite wehenga ara i runga i te ara ki a ratou.

Ngā i runga i kiore nei pau te glycol propylene rā, whakamatauria e kore e pā reira te hauora me te ora o nga mea ora. Heoi, ki te mea he roa te wa ki te whakamahi i te hua me taka kei roto nui o te taonga, ka taea e mamae tākihi, ka kia faaoti ratou mahi, me te tapatahi. Ko kia pau tenei te nui o 100% glycol propylene tino parakore, i te mea o te akoranga e taea.

Na reira, whakaaetia te whakamahi o te waipiro i roto i te ahumahi Paku, kakara me te kai kei te rite ki te tikanga me ngā ture. Te pānga kino anake e taea whai reira i runga i te hunga e mamae i mate kiri, dermatitis, katoatia me ngā puka matatini o te mate pāwera. I roto i tenei take, e kore e tūtohu ana ki te whakamahi i aihikirīmi, hinu, shampoos me ētahi atu hua e roto i te taonga.

Ahumahi Manufacturing

āhuatanga matū tukua propylene ki te whiwhi propylene waikura i reira i raro i etahi tikanga o te pāmahana (200 ⁰ C) me te pēhanga (1.6 MPa). I roto i tenei take i te hua e tika e toru kai:

• propylene glycol;
• glycol;
• tripropylene.

Hoki atu tikanga wehenga ki te tīwae whakatika i motuhake tukatuka me te whakamahia te. Ko te hua oti he uara te viivii tiketike (99%), me reira tonu rite mo te whakamahi. Food propylene glycol te whakamamaetia atu tukatuka, wā rokiroki o runga ki te rua tau.

Whakamahia rite ārai makariri

Tuatahi o te waipiro katoa whakamahia te i roto i te ahumahi rite te kawe wera. Ka taea te whakamahi Propylene glycol i teploustanovkah i roto i te whānuitanga pāmahana i -40 ⁰ C ki 108 ⁰ C. ano, ka taea tona kaha waikura iti ki te mau tonu i te taputapu. Na reira te whakamahia propanediol hoki:

• whakawera;
• conditioning o ngā momo katoa o whare;
• ventilation;
• Te meangiti kai.

Whakamahia i roto i te poke

Ko te kaha o te taonga ki te hopu me te here wai, marara, te whakapai ake kakano, rāpoi kakara kawe niu nei te whakamahi i te reira i roto i te poke me ahumahi mea kakara. I tua atu, i te tauhohenga iti me te haumaru i roto i ngā o te taupuhi kaiao, te whakatau hoki rongoā te whiriwhiri o tenei wae ko ki te waihanga aihikirīmi, shampoos, i peitahia, hinu, me te tahi atu hua.

He maha kamupene e whakaherea ki te hoko propylene glycol. tei Utu i runga i te kukū o te hua, me te nui o te tikanga. pae te reira i 150 ki te 170 moni ia kirokaramu.

Te whakamahi i roto i te ahumahi kai

I roto i te glycol propylene ahumahi kai mohiotia rite E1520. Ko ia he mema o te hua maha e he pasty, ōritetanga kahotea, me te rare mārō. Tona tūranga - marara, tamarûraa, tautauā, kēna.
