Ukuhlola Ukuphepha Kwe-1,3 propanediol

I-1,3 propanediol isetshenziswa kabanzi njengendawo yokwakha ezimbonini ukuze kwenziwe i-polymer nezinye izinhlanganisela ezihlobene.

Kuphinde kube yimpahla eluhlaza ebalulekile ekukhiqizeni iphunga elimnandi, okunamathelayo, opende, imikhiqizo ehlobene nokunakekelwa komzimba njengamakha.

Iphrofayili ye-toxicology yento engenambala nengashi ayinakwa.Yingakho ukusetshenziswa kwawo kunqamula ukudla ezimbonini ezikhiqiza imithi.

Nokho, lapho kutholakala1,3 propanediolngemikhiqizo ehlobene nokunakekelwa komzimba wakho njengokhilimu wezinwele neshampoo, kubalulekile ukuyithenga kubakhiqizi abathembekile.

Lo mhlahlandlela wolwazi owusizo ubheka ukubuka konke kokuphepha kwe-1,3 propanediol.

1,3 Imodi ye-propanediol Yokuchayeka

1.Ukuchayeka emsebenzini

Nakuba i-propanediol ye-1,3 iphathwa ngokucophelela phakathi nenqubo yesicelo sokunciphisa ukuchayeka okungenzeka kubasebenzi kanye nemvelo, abasebenzi bayelulekwa ukuba bahambisane nezinyathelo zokuphepha ezinikeziwe.

Ukwengeza, abasebenzi ezimbonini ezinjalo lapho kusetshenziswa khona i-propanediol ephezulu ye-1,3 kulindeleke ukuthi baqeqeshwe ekuphatheni amakhemikhali okujwayelekile kanye nokulebula.

Nokho, lolu hlelo lokusebenza lwezimboni lwale nto engenambala luqinisekisiwe ukuthi luphephile inqobo nje uma kulandelwa izinyathelo zokuphepha.

2.Ukuchayeka Kwekhasimende

Into engashi ayinakho ukukhathazeka ngokushesha kubantu njengoba ingadli eluhlaza.Noma kunjalo, ivezwa ngokungaqondile endaweni ezungezile.

I-1,3 propanediol ezakhiwe izimpahla ezifana ne-adhesive, lubricant, waxes, sealants, njll., ezithengwe ngabathengi, ziqukethe inani leminithi elingelona ingozi.

3.Ukuchayeka kwemvelo

Ukuqamba okusha kwezobuchwepheshe emkhakheni wezimboni nokuqeqeshwa kwezisebenzi kunciphisa ukuchayeka kwemvelo kwezinto ezingaqhumi, i-1,3 propanediol.

Nokho,1,3 propanediolkufanele iphathwe ngendlela efanele ngesikhathi sokwelashwaukwakhiwa, ukugcinwa, ukuthutha, nezinqubo zokulahla.Ngoba uma ingaphathwa ngendlela efanele, izogcina ibeke imvelo engozini.

Ulwazi Lwezempilo mayelana ne-1,3 propanediol

1.Ukuphatha ngomlomo

Ucwaningo lukhombisa ukuthi ubuthi be-propanediol bomlomo obuyi-1,3 buphansi kakhulu.Kuqinisekisiwe ukuthi inani elikhulu kuphela elidingekayo ukudala izakhiwo zezempilo ezilandelekayo kubantu.

Kodwa-ke, kuyiqiniso elaziwayo ukuthi i-ethanol inobuthi obuphindwe kathathu kune-1,3 propanediol.

2.Ukuphefumula

Ayikho inkomba ye-cancerogenic ye-1,3 propanediol.Kodwa-ke, i-formalin iyikhemikhali okusolwa ukuthi yehlisa izinga le-1,3 propanediol.

Alukho ucwaningo olukhombisa ukuthi uma ukuba khona kwale nhlanganisela kuyingozi uma isemoyeni.

3.Ukusabela kwe-allergic

Ukuvama kwe-1,3 propanediol kulinganiselwa ukuthi kuyaguliswa kusuka ku-0.8% kusisombululo esinamanzi kuya ku-3.5%.

Umbiko wochwepheshe bezempilo ubonisa ukuthi ingxenye yomzimba ethinteka kakhulu uma i-1,3 propanediol ithinta ubuso namehlo.

4.Izilwane

I-1.3 i-propanediol iqinisekiswe njengesengezo sokudla senja.Kodwa-ke, akuvunyelwe ukusetshenziswa ekudleni kwekati ngenxa yesakhiwo somzimba wabo.Futhi, kuthinta amangqamuzana egazi abomvu ekati, ngaleyo ndlela kunciphise ukuphila kwawo.

I-Springchemumphakeli owaziwayo ongaxutshwe nalutho1,3 propanediolngezinhlelo zokusebenza ezihlukene zezimboni, njengezithasiselo zokudla, izimonyo, izinto zokunamathisela, njll.Xhumana nathi ngezidingo zakho ezi-1, 3 ze-propanediol ngemikhiqizo yakho ehlobene nokunakekelwa kwezempilo, futhi ngeke uzisole ngokusebenzisana nathi.
