Dioctyl Terephthalate (DOTP) ipurasitiki yakanakisa ine zvinhu zvakanaka zvemagetsi. Iro vhoriyamu resistivity ndeye gumi kusvika makumi maviri nguva yeDOP. Iyo ine yakanaka plasticizing mhedzisiro uye yakaderera volatility kunyanya mune tambo zvinhu. Inoshandiswa zvakanyanya kune zvakasiyana-siyana zvigadzirwa zvinoda kupisa kupisa uye yakakwirira insulation, yakanakira plasticizer yekugadzirwa kwePVC cable zvinhu.
DOTP zvakare ine yakanaka kutonhora kupikisa, kupisa kupisa, kudhirowa kuramba, volatility kuramba, uye yakakwirira plasticising kunyatsoita. Inoratidza kusimba kwakanyanya, sipo mvura inodzivirira uye yakaderera tembiricha inoshanduka mune zvigadzirwa.
DOTP inogona kusanganiswa neDOP mune chero chiyero.
DOTP inoshandiswa mukugadzira plasticizing paste kuderedza viscosity uye kuwedzera pasherufu hupenyu.
DOTP inogona kuderedza viscosity uye inowedzera kuchengetedza hupenyu kana ichishandiswa muplastisol.
Inonyanya kushandiswa seplasticiser yePVC cable zvinhu.

Dioctyl Terephthalate (DOTP) inofanirwa kurongedzerwa mu200L galvanized iron dhiramu kana iron dhiramu, yakavharwa nepolyethylene kana isina ruvara rubber gaskets. Mamwe mapeji anogonawo kushandiswa zvinoenderana nezvinodiwa nevatengi.
1) Chigadzirwa chacho chichachengetwa munzvimbo yakachena, yakaoma uye ine mhepo yekuchengetera mhepo. Imba yekuchengetera inofanirwa kufefeterwa uye inotonhorera, kudzivirira zuva rakananga, tembiricha yakakwira, humidity inorema, nezvimwe, kudzivirira zvigadzirwa kubva kuzvimba, oxidation uye mamwe matambudziko.
2) Chigadzirwa hachifanirwe kuchengetwa pamwe chete neanoshanda makemikari zvigadzirwa senge acid uye alkali uye zvinhu zvine humidity yakanyanya
3) Tembiricha yekamuri yekuchengetera chigadzirwa inofanira kunge iri (16-35) ℃, uye hunyoro hunofanira kunge huri pasi pe70%
4) Chigadzirwa chacho kamwe kamwe chinoshanduka kubva kunzvimbo yakadzika yekushisa kusvika kune yakakwirira yekushisa panguva yekuchengetedza. Usavhura pasuru yacho nekukurumidza, asi ichengetedze munzvimbo yakaoma kwenguva yakati. Mushure mekunge tembiricha yechigadzirwa ichikwira, vhura pasuru kudzivirira chigadzirwa kubva kune oxidizing.
5) Chigadzirwa chacho chinofanira kunge chakazara zvachose kudzivirira unyoro uye kusvibiswa.
6) Chigadzirwa chacho chichadzivirirwa kubva pakumanikidzwa kukuru uye kumwe kukanganisa kwemagetsi panguva yekuchengetedza.
