Yuav ua li cas TPE Lub Tsev Loj Lub Tsheb Loj Tsav Tsheb hauv Bottarking hauv qis- qhov chaw ib puag ncig?

Kev ua yeeb yam ntawm TPE (thermoplastic elastomer) lub tsev loj tsheb lub log nyob rau hauv qis {{}}}}} Nyob) thiab cov txheej txheem tsim qauv. Zuag qhia tag nrho, cov yam ntxwv kev ua tau zoo yog "cov khoom siv hluav taws xob loj ntau yam kev ua kom sai ntawm cov khoom ua tau zoo me me, thiab tswj tau kev tswj hwm kev ua haujlwm." Qhov no yuav tsum tau txheeb xyuas qhov tshwj xeeb ntawm qhov chaw nres tsheb uas muaj qhov chaw nyob hauv lub caij ntuj no (piv txwv li kev siv tsheb sab nraum zoov hauv lub caij ntuj no ntawm -5℃rau 0 degree):

I. Cov kev ua tau zoo hloov: Qhov cuam tshuam tseem ceeb ntawm tsis kub ntawm TPE Log

Tsawg kub siab qhov kev txav qeeb ntawm tpe molecular chartss, uas nyob rau hauv lem nyuaj, uas nyob rau hauv lem kev cuam tshuam cov khoom tseem ceeb xws li rearsness, thiab dov smoothness. Cov qib ntawm kev ua tsis ncaj ncees nyob ntawm seb cov khoom siv hauv paus:

1. Elastic thiab Hardness thiab Hardness: Sebs-} based tpes ua tau zoo dua qub, thaum sbs} based tpes yog nquag mus rau brittleness.

SBS (Hydrogenated Styrene - butadiene thaiv cov copolymer) {}} kub {3} {ristant qauv):

Qhov qis qis ntawm qis - kub ua tau tuaj yeem mus txog ntawm 40 qib (-5 degree} Dej nyab hardness tsuas yog nce ntxiv los ntawm 5A-10a (piv txwv li, 70a ntawm chav tsev kub txog 75A-80A ntawm tsawg kub). Lub log lub log tseem tuaj yeem deform me ntsis rau cushion av cuam tshuam, tsis muaj kev paub "rigidity embritty."

SBS (Styrene - butadiene thaiv copolymer) {{{{{- tus nqi version):
Qhov qis qis ntawm qis - kub ua rau tsuas yog - 10℃rau 0 degree. Hauv ib puag ncig hauv qab no 0 degree, cov molecular chains nyiam "khov," sai sai poob elasticity. Ntug dej Hardness yuav nce ntxiv los ntawm 15a-25a (li, 70a ntawm chav tsev kub txog 85A-95A ntawm tsawg kub), txawm tias lub xeev semi-rigid. Lub log lub log lub log pom tsis muaj qhov pom tseeb thaum nias, tab sis yog nquag mus rau "kev sib tsoo nyuaj" thaum thawb pob hauv av.

2. Cov ntsiab lus tsis zoo: elasticity poob ua rau muaj zog ntxiv, tshwj xeeb yog nrog sbs - raws cov ntaub ntawv.
TPE lub txiaj ntsig zoo dua kev vam khom rau elastic cushioning. Qhov kev poob ntawm elasticity ntawm tsawg kub ncaj qha nthuav dav cuam tshuam thiab kev sib txhuam nrov:
SBS -} Raws li TPE: Thaum siv nyob rau hauv ib qho chaw txias (5}
SBS -} Raws TPE: Nyob ib ncig ntawm 0 degree, suab qib siab tau nce ntawm 55db ntawm chav tsev kub txog li 650db (zoo ib yam li lub suab luam ntawv). Vim yog lub hardness ntxiv, "nyuaj kev sib txhuam" nrog cov suab siab, tshwj xeeb tshaj yog pom ntawm cov vuas luaj (xws li ceramic vuas) hauv cov chaw cia khoom txias.

3. Hnav thiab kua muag tiv thaiv: nce hardness exacerbates "zos hnav"
Ntawm tsawg kub, tpe's nce hardness thiab txo qis tawv muaj zog txo nws cov kev cuam tshuam thiab kua muag kuj zoo, txhawb kev hnav.
Txhob txwm: Cov ris coefficient ntawm Seb {}}}}}}}}}}} Raws tib qho kub (0.025 cmy / 1.61 km). Yog tias muaj txawm tias me ntsis ntawm te rau hauv pem teb (ib txwm nyob ib ncig ntawm qhov rooj txias Lub kua muag tiv thaiv: ntawm -5 degree, kua muag lub zog ntawm SBS-based tpe dauv los ntawm 18 kn / m ntawm chav tsev kub mus rau qis dua 10 kn / m. Qhov no tuaj yeem ua rau lub log ntug tawg tawg thaum thawb dhau cov pob me ntawm cov hauv paus ntawm cov pob tub yees. Sebs-based TPE lub kua muag tsuas yog txo qis dua li 10% -15% (tseem ntau dua lossis sib npaug nrog kev tawg.

4. Rolling Smoothness: nce tsis kam, thawb hnyav
Ntawm tsawg kub, lub hardness ntawm TPE log nce, txo lawv thaj chaw tiv tauj nrog hauv av thiab nce rolling rolling.
SBS -} Raws TPE: Thaum Rolling tsis nce ntxiv los ntawm chav sov, ua rau hnyav me ntsis, tab sis tseem yooj yim thawb.
SBS -} based tpe: thaum pushing tib lub zog hauv qab 0 degree}} Qhov no yuav tsum muaj zog ntau dua txav mus los, cuam tshuam cov neeg ua haujlwm ua haujlwm tau zoo.

Ii. Cov Khoom Siv Khoom Siv Lub Tsev Nrhiav Lus Qhia: Xam pom kev haum xeeb los ntawm cov xwm txheej
1. Luv - sij hawm / txwv siv
Cov chaw khaws cia rau hauv tub yees (0-10 degree, tsawg dua los yog sib luag rau 10 siv ib hnub):
Ua ntej nrawm -} based tpes nrog siab qis {2} {{}}℃thiab siab dua "). Cov TPES no tuaj yeem ua tau raws li qhov xav tau ntawm "Luv luv- lub sij hawm xaiv" thiab muaj ib lub neej muaj kwv yees li 1 - 1.5 xyoo. Zam kev sos-based tpes, raws li lawv yuav xav tau hloov chaw tom qab 3-6 lub hlis vim embrittlement thiab hnav.
Luv -}}}}} kev thauj mus los sab nraum zoov hauv lub caij ntuj no (-5℃rau 0 degree, ib leeg siv tsawg dua lossis sib npaug li 5 feeb):
Tsuas yog SBS -} based tpes tuaj yeem siv ib ntus (xws li luv- deb tsheb thauj mus los rau lub khw muag khoom). Txawm li cas los xij, tsis txhob muaj ntev ntev ntawm lub log rau qhov kub qis (ib ntus hardness nce tom qab ntau dua 10 feeb, uas tuaj yeem rov qab thaum ua kom sov). Tom qab kev thauj mus los, nws raug nquahu kom tso lub log nyob rau hauv ib cheeb tsam kub nyob rau 30 feeb kom muaj elasticity kom rov zoo ua ntej siv hauv khw muag khoom.

2. Duag zam
Cov chaw tshaj tawm lub freezer (tsawg dua los yog sib npaug ntawm -18 degree, xws li dej khov noj):
Txawm hais tias {-} based tpe yuav dhau los ua kom tawg (hardness - 18 degree, ua rau lub log tawg thaum thawb mus rau hauv av. Rolling tsis kam yog heev heev, ua rau nws siv tau. Hloov nrog qis qis - kub-resistant pu (-20℃rau 80 degree) lossis nylon (-30℃rau 120 degree).
Kev nquag siv sab nraum zoov nyob rau hauv lub caij ntuj no (loj dua los yog sib luag rau 5 zaug hauv ib hnub, loj dua lossis 10 feeb txhua lub sijhawm):
Rov ua dua qis -} kub qhov kis tau yuav ua rau qaug zog thiab kev laus ntawm TPE molecular chains. Txawm hais tias {- bas raws mus tas li nws elasticity tom qab kev ua kom sov), txo qis nws txoj kev ntsiag to thiab hnav tsis kam. Pu cov ntaub ntawv yuav tsum tau nyiam. III. Kev yuav khoom thiab cov kev yuav txiav txim siab
Piav qhia txog cov hom khoom siv hauv paus: thaum kev yuav khoom los piav cov khoom tpe {{
Tshawb xyuas Qis - kub ua kom tsis txhob muaj: part}}}}} raws li feem ntau yog feem ntau ntawm -10℃thiab 0 degree). Qhov qis dua qhov kub tshaj plaws kub, qhov ntau ruaj khov qhov ntsuas kub tsawg.
Kev tswj cov log: Tsis txhob tawm ntawm lub log tpe tsis siv rau ncua sij hawm hauv qis {{}}}}}} kub nyob rau hauv ib lub kaum tsev nyob ntau tshaj 24 teev). Qhov no tuaj yeem ua rau muaj cov hauv zos ua kom tawv nqaij tawv ntawm cov khoom, cuam tshuam rau kev rov qab kho tshiab.
Kev tu tsis tu ncua: Tom qab tsawg - kub siv, nquag so daim ntaub los tshem tawm cov dej khov thiab plua plav kom tiv thaiv cov av los ntawm kev hnav thiab hnav kom tiv thaiv.

Cov ntsiab lus: TPE log kev ua tau zoo hauv cov chaw qis {}}}}}}}}}}} Cov me nyuam thiab lub ntsej muag zoo nkauj yog tseem zoo dua rau nylon. Txawm li cas los xij, SBS - based tpe yog kiag li tsis tsim nyog rau kev siv hauv freezer thaj chaw (tsawg dua lossis sib npaug} 18}} 18}} 18}} 18}} 18 degree). Yog tias cov khw muag khoom nquag siv cov laub nyob hauv qhov chaw qis (xws li muaj cov khoom siv (-) kev kawm kom tsawg dua
