Xyoo tsis ntev los no, cov khoom lag luam yas tau nce ntau hauv peb lub neej. Qee lub plastics yog cov tshuaj lom, thaum lwm tus yog ib puag ncig. Raws li peb txhua tus paub, thermoplastic polyurethane (TPU) yog tus phooj ywg zoo rau yas nrog cov khoom sib txawv rau ntau qib. Hauv kev sib piv, txawm hais tias silicone thiab hluavtaws roj hmab muaj cov khoom sib xws, lawv tsis muaj kev tiv thaiv zoo ib puag ncig zoo li TPU.
Ntawm no peb muaj qee txoj kev kom paub qhov txawv TPU, silicone thiab hluavtaws roj hmab.
TPU:
1. Pob tshab lossis xim.
2. Muaj tus nplaim daj, tawg me me, thiab qhov tsawg yuav nqus pa luam yeeb thaum kub. Tej zaum yuav muaj cov pa luam yeeb dub thaum nws tsis kub tag nrho.
3. Cov tshuaj tsw qab me me.
4. Kev ntsuas qhov nyuaj yog 60A-80D
Silica gel:
1. Muaj qhov ci nplaim ci dawb thaum hlawv.
2. Muaj me ntsis ntxhiab thiab haus luam yeeb thaum hlawv. Qhov seem tom qab hlawv yog hmoov dawb.
3. Qhov hardness ntau yog 10A-90A.
Khoom cua roj hmab:
1. Cov nplaim taws cig yog daj.
2. Nws tsw ntxhiab tsw zoo thaum nws hlawv.
3. Lub hardness ntau yog feem ntau 50A-80A.
