Muaj qee qhov sib txawv ntawm PE lub hnab ntim tus kheej (polyethylene self-adhesive hnab) thiab PP lub hnab nws tus kheej nplaum (polypropylene self-adhesive hnab) hais txog cov khoom siv, kev ua haujlwm, thiab kev siv. Cov hauv qab no yuav muab piv rau ob lub hnab self-adhesive kom ntxaws:
1. Cov khoom sib txawv
PE self-adhesive hnab (polyethylene self-adhesive hnab):
Ua los ntawm cov khoom siv polyethylene (PE), PE yog cov thermoplastic uas muaj kev ywj pheej zoo thiab ua haujlwm ntev.
Qhov saum npoo ntawm PE cov khoom yog smoother thiab pob tshab, thiab feem ntau yog siv rau ntim khoom uas yuav tsum tau muaj zog tiv thaiv thiab ya raws.
PP self-adhesive hnab (polypropylene self-adhesive hnab):
Ua los ntawm cov khoom siv polypropylene (PP), PP yog cov yas tiv taus cua sov thiab tshuaj lom neeg uas muaj qhov tawv tawv dua li PE.
Cov khoom siv PP feem ntau yog nyias dua li PE thiab muaj qhov pom tseeb me ntsis, tab sis muaj zog dua thiab zoo dua tensile kuj.
2. Qhov txawv ntawm lub cev muaj zog
PE self-adhesive hnab:
Flexibility: PE cov ntaub ntawv kuj yog mos, yog li PE lub hnab ntim nws tus kheej muaj kev yooj yim dua thiab tuaj yeem qhwv cov khoom tsis zoo.
Impact resistance: Nws muaj kev cuam tshuam zoo, tuaj yeem tiv thaiv sab nraud zoo, thiab tsis yooj yim tawg.
Tsis tshua muaj kub tsis kam: PE hnab rau tus kheej nplaum tseem tuaj yeem tuav tau zoo softness nyob rau hauv qhov kub thiab txias ib puag ncig, thiab yog haum rau siv scenarios xws li txias saw logistics.
PP self-adhesive hnab:
Rigidity: PP cov khoom yog nruj dua li PE, PP lub hnab ntim tus kheej yog cov tawv tawv thiab tsis yooj yim rau khoov, thiab tsim nyog rau cov khoom ntim nrog cov qauv tsis tu ncua.
Thaum tshav kub kub tsis kam: PP lub hnab nws tus kheej nplaum muaj qhov ua kom sov zoo, tuaj yeem tiv taus qhov kub thiab txias, thiab tsim nyog siv rau hauv qhov kub thiab txias.
Cov kua muag tsis kam: PP hnab muaj qhov tensile thiab tsim kua muag zoo dua li PE hnab, tab sis me ntsis cuam tshuam tsis zoo dua li PE.
3. Pob tshab
PE hnab ntim tus kheej: Lawv feem ntau muaj qhov pom tseeb dua, pom meej meej cov ntsiab lus ntim, thiab muab cov neeg siv khoom pom kev zoo dua. Lawv tsim nyog rau lub sijhawm xws li khoom noj khoom haus thiab tshuaj pleev ib ce uas yuav tsum tau ua kom pom tseeb.
PP hnab rau tus kheej nplaum: PP lub hnab nws tus kheej nplaum muaj qhov pom tseeb me ntsis thiab lub ntsej muag muaj zog dua, tab sis vim yog lawv cov khoom, qee zaum lawv yuav tshwm sim me ntsis dawb los yog pos huab me ntsis.
4. Huab cua tsis kam thiab ib puag ncig adaptability
PE hnab ntim tus kheej: PE hnab muaj huab cua nruab nrab thiab muaj kev cuam tshuam ntau dua rau ib puag ncig xws li ultraviolet rays thiab oxidation. Lawv yog cov nquag laus thaum raug tshav ntuj ntev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig sab nraum zoov, thiab tsis zoo li PP hnab.
PP lub hnab ntim tus kheej: PP cov ntaub ntawv muaj huab cua tsis zoo thiab muaj zog tiv thaiv ultraviolet kev ua tau zoo, thiab tsim nyog rau kev siv mus ntev hauv qhov chaw hnyav (xws li kub kub, ncaj qha tshav ntuj, thiab lwm yam).
5. Scope ntawm daim ntawv thov thiab siv
PE self-adhesive hnab:
Haum rau ntim khoom muag xws li khaub ncaws, ris tsho hauv qab, khoom noj (xws li txiv ntseej, khoom qab zib, khoom qhuav), khoom siv me me, thiab lwm yam.
Vim nws qhov yooj yim thiab ya raws tsis kam, PE hnab kuj tseem siv tau rau ntim cov khoom ntim rau hauv tub yees lossis kub qis.
PP self-adhesive hnab:
Ntau qhov tsim nyog rau cov khoom ntim nrog cov kev xav tau siab dua rau kev tiv thaiv tshav kub thiab tensile kuj, xws li phau ntawv, ntawv sau, qhov chaw thiab lwm yam khoom nyuaj.
PP hnab feem ntau yog siv los ntim cov khoom siv hluav taws xob, cov khoom siv me me, cov khoom muag, thiab lwm yam, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias los yog kev sib cuag ncaj qha nrog cov khoom siv hluav taws xob, PP hnab ua haujlwm zoo.
6. Kev tiv thaiv ib puag ncig
PE self-adhesive hnab: PE cov ntaub ntawv yog ib qho yooj yim rau recycle, tab sis vim lawv tsis tshua muaj ceev, tus nqi rov ua dua yog tsawg. Nyob rau hauv xyoo tas los no, kev tiv thaiv ib puag ncig ntawm PE hnab tau txhim kho, thiab qee lub tuam txhab muab cov hnab PE degradable.
PP hnab rau tus kheej nplaum: PP hnab yog ib puag ncig zoo thiab muaj kev rov ua dua tshiab. PP yog ib qho ntawm cov khoom siv yas zoo tshaj plaws nyob rau tam sim no, thiab PP hnab yog yooj yim los lis thiab siv dua li PE hnab.
7. Nqe
PE hnab ntim tus kheej: PE hnab feem ntau pheej yig dua thiab tsim nyog rau kev tsim khoom loj thiab cov nqi ntim qis.
PP hnab rau tus kheej nplaum: PP hnab feem ntau yog me ntsis kim dua vim lawv cov ntaub ntawv ruaj khov thiab siab rigidity.
PE self-adhesive hnab yog tsim rau cov mos mos thiab tsis tshua xav tau ntim txhua hnub, thaum lub hnab PP tus kheej nplaum yog tsim rau cov khoom ntim uas xav tau siab pob tshab, kub tsis kam lossis siab tensile tsis kam. Xaiv ob qho raws li kev siv sib txawv tuaj yeem txhim kho cov nyhuv ntim thiab kev tiv thaiv cov khoom.
