Vulawuri bya Viscosity eka PET Strap: Ha yini 0.60–0.95 dl/g yiri ya nkoka eka Matimba

Nomboro Leyi Fihliweke Endzhaku Ka Matimba Ya PET Strap

Loko vaxavi va boxa PET strap (polyester strap), hi ntolovelo ti languta eka ti metrics leti vonakaka: ku anama, ku enta, na matimba yo tshoveka. Hambiswiritano, matirhelo ya michini ya bandi leri hetiweke hi xisekelo ya lawuriwa hi ku hlamuseriwa loku nga vonakiki ka swilo leswi nga tirhisiwangiki: intrinsic viscosity (IV) ..

Viscosity i mpimo wa ntiko wa molecule ya polyester resin. Swi boha leswaku ti polymer chains ti lehe ku fikela kwihi na leswaku ti hlangana hi matimba ku fikela kwihi. Eka indasitiri ya strapping, ndzhawu yo tsokombela ya khwalithi yale henhla ya PET strap i viscosity range ya 0.60 kuya eka 0.95 dl/g.

Loko viscosity yiri ehansi swinene, ti polymer chains ti komile, leswi endlaka leswaku kuva na strap leyi pfumalaka tensile strength naswona yinga tshoveka hiku olova. Loko viscosity yiri e henhla swinene, resin yiva yi tiya swinene leswaku yinga tirhisi kahle, leswi endlaka leswaku kuva na swihoxo eka vumaki.

Eka Jushuo Packaging, data ya hina ya vuhumelerisi yikombisa leswaku ku hlayisa vulawuri byo tika bya viscosity exikarhi ka 0.60 na 0.95 dl/g i swa nkoka eka ku humelerisa strapping leyinga siva nsimbi eka switirhisiwa swo tika.

1. Xana Intrinsic Viscosity I Yini?

1.1 Nhlamuselo na Ku pima

Intrinsic viscosity (IV) i mpimo wa vuswikoti bya polymer byo khuluka eka solution, leswi fambelanaka hiku kongoma na ntiko wa yona wa molecule. Hikuya hi misinya ya milawu ya sayense ya polymer, IV hi ntolovelo yi pimiwa hi ti deciliters hi gram (dl/g). Eka PET resin leyi tirhisiwaka eka strapping, mpimo wukombisa degree ya polymerization.

1.2 Ha yini Viscosity yi hunguteka hi nkarhi wa ku lulamisiwa

Hi nkarhi wa extrusion process, PET resin yi n’okisiwa eka mahiselo yale henhla. Kuya hi ti khemikhali ta vumaki, kuhisa na ndzhongho swinga endla leswaku kuva na hydrolysis, ku tshoveka ti polymer chains xikan’we naku hunguta viscosity. Handle ka vulawuri lebyi faneleke, strap leyi hetiweke yingava na viscosity yale hansi kutlula raw material, leswi endlaka leswaku kuhunguteka swivumbeko swa michini.

2. Ntirho wa Viscosity eka Matimba ya Strap

2.1 Matimba ya ku tsana

Matimba ya tensile ya fambelana hiku kongoma na ntiko wa molecule. Ti polymer chains to leha (viscosity yale henhla) ti endla tindzhawu totala ta entanglement, leti lwisanaka na ku tshoveka ehansi ka tension. PET strap leyingana viscosity ya 0.80 dl/g hi ntolovelo yita tlula strap leyi endliweke kusuka eka 0.60 dl/g resin hiku ya hi matimba yo tshoveka xikan’we naku lwisana na ku khumbeka.

2.2 Ku Engetela na ku Khoma Ntshikelelo

Viscosity yitlhela yi khumba ndlela leyi strap yi ololokaka ha yona. High-viscosity PET yikombisa ku antswa ka elastic recovery, leswivulaka leswaku yi hlayisa tension hiku famba ka nkarhi loko ndzhwalo wutshamiseka. PET ya low-viscosity yinga ololoka hilaha kunga heriki, leswi endlaka leswaku kuva na ndzhwalo lowu ntshunxekeke hinkarhi wa ku hundziseriwa.

2.3 Ku lwisana na mbango

Kuya hi data ya sayense ya swilo, PET ya viscosity yale henhla yi lwisana na ku onhaka ka UV xikan’we naku dyuhala hi mahiselo ku antswa kutlula tigiredi ta viscosity yale hansi. Leswi switiyisisa leswaku strap yi hlayisa matimba ya yona hinkarhi wa vuhlayiselo byale handle bya nkarhi woleha kumbe ku hundziseriwa elwandle.

3. Vuyelo bya Viscosity leyi nga riki yona

3.1 Loko Viscosity Yiri Ehansi Swinene (< 0.60 dl/g) .

• Brittle strap : Strap yinga pandzeka kumbe ku avana hi nkarhi wa tensioning.

• Matimba yale hansi yo tshoveka : Xirhendzevutani xi tsandzeka ehansi ka ndzhwalo lowu bandi leri boxiweke kahle ringa wu khomaka.

• Matirhelo lawa yanga fambelaniki : Ku hambana ka ntlawa kuya eka ntlawa swivanga ku yima ka layini ya vuhumelerisi.

3.2 Loko Viscosity yiri e henhla swinene (> 0.95 dl/g) .

• Timhaka ta vukorhokeri : Resin ya viscosity yale henhla swa tika ku extrude na stretch, leswi yisaka eka ku tirhisiwa ka eneji yale henhla xikan’we naku onhaka ka switirhisiwa.

• Ku tiya : Xirhendzevutani xinga tiya swinene leswaku xinga fambelani na swivumbeko swa phasela, leswi hungutaka ku tiya ka ndzhwalo.

4. Ndlela leyi Jushuo Packaging yi Lawula Viscosity Ha yona

Eka Jushuo Packaging, ahi siyi viscosity eka xitshuketa. Hi tirhisa thekinoloji ya Solid State Polymerization (SSP) ku lawula na ku tiyisisa viscosity ya le ndzeni ya resin ya hina ya PET.

Kuya hi data ya hina ya vuhumelerisi, thekinoloji ya SSP yihi pfumelela ku lulamisa kahle viscosity endzeni ka 0.60 kuya eka 0.95 dl/g range. Leswi switiyisisa leswaku ntlawa wun’wana na wun’wana wa PET strap wu fikelela matimba ya tensile lawa ya kongomisiweke na ku tiya. Hi tiyisisa viscosity hiku tirhisa swikambelo swo tika swa laboratory, ku tiyisisa leswaku strap leyi hetiweke yi tisa matirhelo lawa ya lavekaka eka switirhisiwa swa ti indasitiri leswi tirhaka swinene.

5. Ku kambela Vulawuri bya Viscosity ya Muphakeri

5.1 Matsalwa ya matsalwa

Loko u hlawula muphakeri wa PET strap, kombela swihlawulekisi swa raw material. Muphakeri wo tshembheka uta nyika matsalwa ya viscosity ya le ndzeni ya resin xikan’we na swivumbeko swa michini swa strap leyi hetiweke. Ku va erivaleni loku ku kombisa leswaku vulawuri bya viscosity i xiphemu xa sisiteme ya vona ya vulawuri bya khwalithi.

5.2 Ku Kamberiwa ka Xikombiso

Kombela swikombiso ivi u swi kambela. Hi ku ya hi maendlelo lamanene ya khwalithi:

1. Tensile Test : Tiyisisa leswaku matimba yo tshoveka ya fambelana na xihlawulekisi.

2. Elongation Test : Pima leswaku strap yi ololoka ku fikela kwihi ehansi ka ndzhwalo.

3. Ku Kamberiwa hi mahlo : Languta swihoxo swale henhla leswinga kombisaka ku lulamisiwa lokunga kahle.

Nkomiso

Intrinsic viscosity i specification leyi fihliweke leyi lawulaka matimba ya ntiyiso ya PET strap (polyester strap). Nhlayo ya kahle ya 0.60 kuya eka 0.95 dl/g yitiyisisa leswaku ti polymer chains ti lehe swinene kuva tinyika matimba yale henhla ya tensile xikan’we naku vuyiseriwa ka elastic, loko yirikarhi yitshama yirikarhi yi lulamisiwa kuva yi endliwa vumaki lebyi tshembekaka.

Eka vaxavi, ku twisisa viscosity swi pfuneta ku hambanyisa exikarhi ka vaphakeri va xiyimo xale henhla na lava va tsemaka tikhoneni. Hiku tiyisisa vulawuri bya viscosity, unga tiyisisa leswaku PET strap leyi uyi xavaka yita tirha hiku tshembheka eka switirhisiwa leswi lavaka.

Jushuo Packaging yi yime tanihi muendli wa wena wa swirhendzevutani swa polyester PET loyi a tshembekaka, a tisa swintshuxo swa khwalithi ya le henhla swa swirhendzevutani swa pulasitiki leswi seketeriwaka hi ku tlula khume ra malembe ya vutshila byo hlawuleka. Xitirhisiwa xa hina xa xiyimo xa le henhla xa vumaki xa 15,000m2 xi tirhisa thekinoloji ya xiyimo xa le henhla ya Solid State Polymerization (SSP) ku lawula kahle viscosity kusuka eka 0.60 kuya eka 0.95 dl/g, ku humelerisa PET strapping ya matirhelo yale henhla na 99% wa ti pass rates. Hi vuswikoti bya vuhumelerisi bya lembe na lembe lebyi tlulaka 20,000 wa tithani, hi tiyisisa tikheteni ta mphakelo leti tshembekaka na minxavo yo phikizana eka tioda ta xitalo. Loko u lava mpfuneto eka swihlawulekisi swa PET strap kumbe ku tiyisisiwa ka viscosity, hi kombela u rhumela email eka sales@jushuopackaging.com , naswona ntlawa wa hina wa xiphurofexinali wu ta nyika nseketelo wa munhu hi xiyexe.
