Tej zaum yuav muaj qee cov phooj ywg uas tsis to taub lo lus polyethylene siv quav ciab . Ntawm no peb yuav xub qhia seb PE wax yog dab tsi. PE wax yog ib qho hnyav molecular polyethylene, nrog rau qhov hnyav molecular txog 2000-5000, thiab hydrocarbon sib tov nrog cov pa roj carbon atom ntawm li 18-30. Cov khoom tseem ceeb yog linear alkanes (kwv yees li 80% - 95%), thiab ib tug me me ntawm alkanes nrog ib tug ceg thiab monocyclic cycloalkanes nrog ntev sab chains (tag nrho cov ntsiab lus ntawm ob yog tsawg tshaj li 20%). Tom qab ntawd, tom qab nkag siab txog PE wax, peb yuav rov qab mus rau lub ntsiab lus tseem ceeb thiab qhia seb yuav ua li cas thiaj paub qhov tseeb thiab tsis tseeb PE wax.

1. Flake polyethylene wax
Qhov tiag flaked polyethylene wax nqaij zoo li yas. Nws zoo nkaus li nyuaj thiab zoo ib yam li cov khoom yas. Qhov saum npoo yog du, translucent, ntuj dawb los yog daj. Thaum koj saib nws, koj yuav pom tias tsis muaj txheej txheej sab hauv, tsis muaj txiv qaub hmoov, cov pob dub thiab lwm yam impurities, thiab muaj qhov ci zoo thaum koj saib nrog lub teeb;
2. Kov nrog koj txhais tes
Tiag polyethylene wax muaj smoothness zoo. Nws zoo li yas ntau dua li siv quav ciab. Nws yog ib qho nyuaj, nkig, yooj yim tawg, thiab tsis agglomerate ntawm qhov kub thiab txias. Fakes uas muaj paraffin, hardened roj thiab Fischer Tropsch wax yog greasy. Lawv hnov ​​oily thiab zoo li tswm ciab, los yog lawv saib ntxhib thiab mos. Yog tias lawv nyob hauv cov hmoov, lawv yuav tsim ib pawg thaum koj tuav lawv nrog koj txhais tes.

3.
Cov ntxhiab tsw tiag tiag polyethylene wax tsw zoo li cov yas, thaum cov khoom cuav polyethylene wax tsw zoo li cov quav ciab lossis muaj ntxhiab tsw zoo;
4. Boil nyob rau hauv boiling dej
Muab cov khoom siv quav ciab tso rau hauv ib khob khob thiab kub kom txog thaum cov dej boils rau 5 feeb. Qhov tiag polyethylene wax yog ib qho uas nws cov duab tseem tsis hloov, thiab polyethylene wax uas muaj impurities xws li paraffin wax yog ib qho uas ua nplaum los yog deformed. Txawm hais tias cov txheej txheem kev sim sib txawv thiab qhov chaw sim sib txawv, qhov muag muag ntawm cov khoom tiag yuav tsum siab dua 100 ℃.
5. Siv lub ntsuas cua melting point, infrared spectrometer thiab nuclear magnetic resonance test
Lub melting point ntawm tiag polyethylene wax yog feem ntau txog 105 degrees, thiab cov melting ntau yog nqaim. Cov khoom cuav sib xyaw nrog lwm cov khoom muaj qhov tsis tshua muaj melting point thiab dav melting ntau. Lub infrared spectrometer zoo li lub qhov muag kub. Nws yog ib qho yooj yim kom paub qhov tseeb ntawm qhov tsis tseeb, tab sis cov cuab yeej yog kim. Tsis hais txog nuclear magnetic resonance.
6. Qhov tseeb ntawm polyethylene wax tau sim los ntawm kev ntsuas qhov sib txawv ntawm qhov sib txawv, qhov muag muag, cov nqi kua qaub thiab cov hmoov tshauv;

7. Sim
Tus nqi ntawm cov ntshiab PE wax yog me me, cov khoom demoulding yog qhov zoo, cov khoom tsis yog precipitated, thiab brightness ntawm cov khoom yog siab, thiab ntau yam khoom ntawm cov khoom yog txhim kho. Fake PE wax tsis muaj cov khoom zoo tshaj no.
Muaj ntau txoj hauv kev los txheeb xyuas qhov tseeb thiab tsis tseeb PE ciab. Feem ntau, nws yog: ib saib, ob kov, peb tsis hnov ​​tsw, plaub boil, tsib xeem thiab rau sim.
Qingdao Sainuo Chemical Co., Ltd. Peb yog cov chaw tsim khoom rau PE ciab, PP ciab, OPE ciab, EVA ciab, PEMA, EBS, Zinc / Calcium Stearate .... Peb cov khoom tau dhau los ntawm REACH, ROHS, PAHS, FDA kuaj.
Sainuo so assured ciab, zoo siab txais tos koj nug!
