Viscosity Kudzora muPET Strap: Nei 0.60–0.95 dl/g Nyaya Dzekusimba

Nhamba Yakavanzika Kuseri kwePET Strap Strength

Apo vatengi vanotsanangura PET tambo (polyester tambo), vanowanzo tarisa ma metrics anooneka: hupamhi, ukobvu, uye kutyora simba. Nekudaro, kuita kwemakanika kwetambo yakapedzwa kunotemerwa zvakanyanya neisingaonekwe kutsanangurwa kweiyo mbishi zvinhu: intrinsic viscosity (IV).

Viscosity chiyero chehuremu hwemamorekuru epolyester resin. Inotaridza kuti macheni epolymer akareba sei uye kuti akabatana zvakadii kune mumwe nemumwe. Muindasitiri yekusungirira, nzvimbo inotapira yemhando yepamusoro yePET tambo ndeye viscosity renji ye0.60 kusvika 0.95 dl/g..

Kana viscosity yakadzikira, cheni dzepolymer ipfupi, zvichikonzera tambo inoshaya simba rekusimba uye inogona kudambuka nyore. Kana iyo viscosity yakanyanya kukwirira, resin inova yakanyanya kuomarara kuti igadzirise nemazvo, zvichikonzera kukanganisa kwekugadzira.

PaJushuo Packaging, data redu rekugadzira rinoratidza kuti kuchengetedza kwakasimba viscosity control pakati pe0.60 uye 0.95 dl/g kwakakosha pakugadzira tambo inogona kutsiva simbi mune inorema-basa kunyorera.

1. Chii chinonzi Intrinsic Viscosity?

1.1 Tsanangudzo uye kuyerwa

Intrinsic viscosity (IV) chiyero chekugona kwepolymer kuyerera mumushonga, unopindirana zvakananga nehuremu hwayo. Zvinoenderana nemisimboti yepolymer sainzi, IV inowanzoyerwa mumadesilita pagiramu (dl/g). Kune PET resin inoshandiswa mukusunga, kuyerwa kunoratidza dhigirii repolymerization.

1.2 Nei Viscosity Inodonha Panguva Yekugadzirisa

Munguva ye extrusion process, PET resin inonyungudutswa pakupisa kwakanyanya. Zvinoenderana nekugadzira chemistry, kupisa uye hunyoro zvinogona kukonzera hydrolysis, kutyora polymer cheni uye kudzikisa viscosity. Pasina kutonga kwakakodzera, tambo yakapedzwa inogona kunge iine yakaderera viscosity pane iyo yakasvibira, inotungamira kune yakaderedzwa ma mechanical properties.

2. Basa reViscosity muStep Strength

2.1 Tensile Simba

Kusimba kwesimba kunoenderana zvakananga neuremu hwemamorekuru. Akareba polymer cheni (yakakwirira viscosity) inogadzira akawanda entanglement mapoinzi, ayo anoramba kutyoka pasi pekukakavadzana. A PET tambo ine viscosity ye0.80 dl/g inowanzopfuura tambo yakagadzirwa kubva ku0.60 dl/g resin maererano nekupwanya simba uye kukanganisa kupikisa.

2.2 Elongation uye Tension Retention

Viscosity inokanganisawo kuti tambo inotambanudzwa sei. Yakakwira-viscosity PET inoratidza zvirinani elastic kupora, zvichireva kuti inochengetedza kushushikana nekufamba kwenguva sezvo mitoro inogadzikana. Yakaderera-viscosity PET inogona kutambanudza zvachose, zvichitungamira kune yakasununguka mitoro panguva yekufamba.

2.3 Kuramba Kwezvakatipoteredza

Zvinoenderana neruzivo rwesainzi data, yakakwira viscosity PET inoramba kuderedzwa kweUV uye kuchembera kwemafuta zviri nani pane yakaderera viscosity mamakisi. Izvi zvinoita kuti tambo ichengetedze simba rayo panguva yekuchengetwa kwekunze kwenguva refu kana kufamba kwegungwa.

3. Mhedzisiro yeViscosity Yakashata

3.1 Kana Viscosity Yakanyanya Kuderera (<0.60 dl/g)

• Brittle strap : Iyo tambo inogona kutsemuka kana kupatsanuka panguva yekumanikidzana.

• Low break force : Iyo tambo inokundikana pasi pemitoro iyo yakanyatsotsanangurwa tambo inogona kubata.

• Kuita kusingaenderani : Batch-to-batch mutsauko unokonzeresa kumira mutsetse wekugadzira.

3.2 Kana Viscosity Yakanyanya Kunyanya (> 0.95 dl/g)

• Kugadzirisa nyaya : Yakakwira viscosity resin yakaoma kuita extrude uye kutambanudza, zvichitungamira kune yakakwira simba rekushandisa uye kupfeka kwemidziyo.

• Kuomarara : Iyo tambo inogona kunge yakanyanya kuomarara kuti ienderane nemapakeji maumbirwo, ichideredza kugadzikana kwemutoro.

4. Sei Jushuo Packaging Inodzora Viscosity

PaJushuo Packaging, isu hatisiyi viscosity mukana. Isu tinoshandisa Solid State Polymerization (SSP) tekinoroji kudzora uye kudzikamisa iyo yemukati viscosity yePET resin yedu.

Zvinoenderana nedata redu rekugadzira, tekinoroji yeSSP inotibvumira kunyatsogadzirisa viscosity mukati meiyo 0.60 kusvika 0.95 dl/g renji. Izvi zvinova nechokwadi chekuti batch yega yega yePET tambo inowana chinangwa chekusimba uye kusimba. Isu tinoonesa viscosity kuburikidza nekuomesesa murabhoritari kuyedzwa, kuve nechokwadi chekuti tambo yapera inopa mashandiro anodiwa kune inorema-basa maindasitiri kunyorera.

5. Kuongorora Supplier Viscosity Control

5.1 Zvinyorwa

Paunenge uchisarudza PET strap supplier, bvunza iyo yakabikwa zvinhu zvakatemwa. Mutengesi anovimbika anozopa zvinyorwa zve resin's intrinsic viscosity uye yakapedzwa tambo yemagetsi zvivakwa. Uku kubuda pachena kunoratidza kuti viscosity control chikamu chemhando yavo yekutonga system.

5.2 Sample Testing

Kumbira masampuli uye woaedza. Zvinoenderana nemhando yepamusoro maitiro:

1. Tensile Muedzo : Simbisa simba rekupwanya rinoenderana nezvakatsanangurwa.

2. Elongation Muedzo : Edza kuti yakawanda sei tambo inotambanudza pasi pemutoro.

3. Visual Inspection : Tarisa uone kuremara kwepamusoro kunogona kuratidza kusagadziriswa zvakanaka.

Summary

Intrinsic viscosity ndiyo yakavanzika yakavanzika iyo inosarudza simba rechokwadi rePET strap (polyester strap). Iyo yakakwana huwandu hwe0.60 kusvika 0.95 dl/g inova nechokwadi chekuti macheni epolymer akareba zvakakwana kuti ape simba rakanyanya kusimba uye kudzoreredza kupora, uku ichiramba ichigadziriswa kugadzira yakavimbika.

Kune vatengi, kunzwisisa viscosity kunobatsira kusiyanisa pakati pevatengesi vemhando yepamusoro uye avo vanocheka makona. Nekuonesa viscosity control, unogona kuve nechokwadi chekuti PET tambo yaunotenga ichaita nekuvimbika mukuda maapplication.

Jushuo Packaging inomira sewako wakavimbika wepolyester PET tambo mugadziri, achiunza emhando yepamusoro epurasitiki tambo zvigadziriso zvinotsigirwa neanopfuura makore gumi ehunyanzvi hunyanzvi. Yedu-ye-ye-iyo-yepamusoro-gumi neshanu ㎡ yekugadzira nzvimbo inoshandisa advanced Solid State Polymerization (SSP) tekinoroji kunyatso kudzora viscosity kubva 0.60 kusvika 0.95 dl/g, inogadzira yepamusoro-inoshanda PET tambo ine 99% kupasa mitengo. Nepagore kugadzirwa kwesimba kunodarika zviuru makumi maviri zvematani, isu tinovimbisa yakavimbika yekugovera cheni uye inokwikwidza mitengo yemaodha akawanda. Kana uchida rubatsiro nePET strap specifications kana viscosity verification, tapota tumira email kune sales@jushuopackaging.com , uye timu yedu yehunyanzvi ichapa rutsigiro rwemunhu-pamwe.
