I-Dioctyl Terephthalate (DOTP)

I-Dioctyl Terephthalate (DOTP), eyaziwa nangokuthi i-Bis(2-ethylhexyl) terephthalate noma i-DEHT, iyipulasitiki esebenza kahle, engena-phthalate eyenzelwe i-PVC eguquguqukayo nezinye izinhlelo zokusebenza ze-polymer. I-DOTP isebenza njengendlela eqondile, eco-friendly esikhundleni samapulasitiki omdabu we-ortho-phthalate afana ne-DOP (DEHP) ne-DINP. Inikeza ukuguquguquka okuhle kakhulu, ukuzinza okushisayo, ukuguquguquka okuphansi, nokumelana nokufuduka okuphakeme ngenkathi ihlangabezana nemithetho eqinile yomhlaba wonke yokuphepha nokuthotshelwa kwemvelo.

I-DOTP iwuketshezi olungenambala, olungenaphunga, olune-viscous oluhlanganisa ngaphandle komthungo ekwakhiweni kwe-PVC, lwehlisa izinga lokushisa lokushintsha kwengilazi futhi luthuthukisa ukuqhubekela phambili. Isakhiwo sayo se-symmetric para-terephthalate sinomthelela ekuguqukeni okuphansi kanye nokuqina okungcono kwesikhathi eside uma kuqhathaniswa namaplastiki amaningi avamile.

Izinzuzo ze-DOTP Ngaphezu kwama-Phthalates Endabuko

Ubuthi obungenayo i-Phthalate nobuncane:

Akukho okuqukethwe kwe-ortho-phthalate; ingcuphe yokuphazamiseka kwe-endocrine kanye nephrofayili yobuthi ephansi uma kuqhathaniswa ne-DOP/DEHP.

I-Superior Thermal Stability & Low Volatility:

Ukumelana nokushisa okungcono kanye nokulahlekelwa kokuhwamuka okuphansi kakhulu ngesikhathi sokucubungula nokusebenzisa ekugcineni.

Ukumelana Nokufuduka Okuhle Kakhulu:

Amazinga okufuduka aphansi aqinisekisa ukuguquguquka kwesikhathi eside futhi avimbele ukuqhakaza kwendawo emikhiqizweni ephelile.

Ukusebenza Okuthuthukisiwe Kwezinga Lokushisa Okubandayo:

Igcina ukuguquguquka emazingeni okushisa aphansi ngaphandle kokuqina.

Ukufakwa Kagesi Okuvelele:

Isici esiphansi se-dielectric kanye ne-dissipation factor, ilungele ukusetshenziswa kwezintambo nezintambo.

Izicelo Eziyinhloko ze-Dioctyl Terephthalate (DOTP)

Ukufakwa kwentambo nekhebula:

Ukumelana nokushisa okuphezulu kufika ku-70-105°C izilinganiso, intuthu ephansi, nezinto ezinhle kakhulu zikagesi.

Izembozo zaphansi nezibonda:

Amashidi namathayela ahlala isikhathi eside, afudukayo kancane.

Ingaphakathi Lezimoto:

Inkungu ephansi, amadeshibhodi anganuki, amaphaneli eminyango, nokunquma.

Isikhumba Sokwenziwa Namafilimu:

Ukuguquguquka okuphezulu, ukuzwa kahle kwesandla, nokusebenza okuphikisana nokukhipha.

Amadivayisi Ezokwelapha namashubhu:

Okunye okuphephile kokungekona ukudla bese ukhetha i-PVC eguquguqukayo yezinga lezokwelapha.

Amathoyizi Nemikhiqizo Yokunakekela Izingane:

Ihambisana nemikhawulo ye-phthalate yezimpahla eziphephile zabathengi.

Izindwangu, Izinamathiselo nama-Sealants:

Igcina ukucwebezela nokuhambisana ekwenziweni.

Imibuzo Evame Ukubuzwa (FAQs)

Q:  Iyini i-Dioctyl Terephthalate (DOTP)?

A:  I-DOTP iyi-plasticizer ye-diester ekhiqizwa yi-esterification ye-terephthalic acid (noma i-dimethyl terephthalate) ne-2-ethylhexanol. Kuyinhlanganisela engeyona i-phthalate (i-CAS 6422-86-2) esetshenziselwa ngokuyinhloko ukuthambisa i-PVC futhi inikeze ukuguquguquka, ukuqina, nokucutshungulwa.

Q: Injani i-DOTP uma iqhathaniswa ne-DOP (DEHP)?

A: I-DOTP idlula i-DOP ekuzinzeni kokushisa, ukuguquguquka, ukumelana nokufuduka, nokuguquguquka kwezinga lokushisa eliphansi ngenkathi inikeza iphrofayela ephephile, engeyona i-phthalate. I-DOP ihlinzeka ngokusebenza kahle kwe-plasticizing ephakeme kancane kwezinye izimo kodwa ibhekana nemikhawulo yokulawula ngenxa yokukhathazeka ngobuthi.

Umbuzo: Ingabe i-DOTP iphephile futhi ayinabo ubuthi?

A: Yebo, i-DOTP ibhekwa njengokuphazamiseka okungeyona eye-endocrine. Ayinayo imiphumela yokwanda kwe-peroxisome ebonwa kwamanye ama-ortho-phthalates futhi ithobela izindinganiso ezinkulu zokuphepha zokuthintana nokudla, amathoyizi, nezicelo zezokwelapha.

Q: Yiziphi izinzuzo eziyinhloko ze-DOTP ezinhlelweni ze-PVC?

A: I-DOTP iletha ukumelana nokushisa, ukumelana nokubanda, ukuguquguquka okuphansi, ukulwa nokukhipha, ukufakwa kukagesi, kanye nokuqina okuphelele okungaphezu kwamapulasitiki amaningi endabuko, okwenza kube kuhle ekusebenzeni okuphezulu nokulawulwa kokusetshenziswa kokugcina.

Q: Kufanele igcinwe futhi isingathwe kanjani i-DOTP?

IMP: Gcina ezitsheni ezivalwe ngci endaweni epholile, eyomile, engenamoya kahle kude nokushisa, amalangabi, nama-oxidizing agents.
