PET Strap-a Viscosity Control: Engvangin nge 0.60–0.95 dl/g hi chakna atan a pawimawh

PET Strap chakna hnuaia Number thup awm

Buyers ten an specify hunah PET strap (polyester strap), an en tlangpui chu hmuh theih metrics: a zau zawng, a thickness, leh break force te an en thin. Mahse, a siam zawh tawh strap-a mechanical performance chu a bulpui berah chuan raw material hmuh theih loh specification-in a thunun a ni: intrinsic viscosity (IV) ..

Viscosity hi polyester resin molecular weight tehna a ni. Polymer chain te hi eng chen nge an sei tih leh eng chen nge an inzawm tlat tih a hril a ni. Strapping industry-ah chuan PET strap quality sang tak siamna atana sweet spot chu viscosity range 0.60 atanga 0.95 dl/g inkar a ni.

Viscosity a hniam lutuk chuan polymer chain te chu a tawi a, chu chuan strap a siam a, tensile strength a tlachham a, awlsam takin a chhe thei bawk. Viscosity a san lutuk chuan resin chu a khauh lutuk a, a process tha thei lo a, chu chuan manufacturing defects a thlen thin.

Jushuo Packaging-ah hian kan production data atanga a lan dan chuan heavy-duty application-a steel thlak thei tur strapping siam nan 0.60 leh 0.95 dl/g inkar viscosity control khauh tak neih hi a pawimawh hle.

1. Intrinsic Viscosity hi eng nge ni?

1.1 Thuhmahruai leh tehna

Intrinsic viscosity (IV) hi polymer pakhat solution chhunga a luang chhuah theihna tehna a ni a, chu chu a molecular weight nen a inzawm tlat a ni. Polymer science principle ang chuan IV hi gram khatah deciliter (dl/g)-a teh a ni tlangpui. Strapping-a hman PET resin tan chuan tehna hian polymerization degree a tarlang a ni.

1.2 Processing laiin Viscosity a tlahniam chhan

Extrusion process chhung hian PET resin chu temperature sang takah a hmin a. Manufacturing chemistry atanga a lan dan chuan heat leh moisture hian hydrolysis a thlen thei a, polymer chain te a tichhia a, viscosity a tihhniam thei bawk. Control tha tak a awm loh chuan strap siam zawh tawh hian raw material aiin viscosity a nei tlem zawk thei a, chu chuan mechanical property a tihhniam phah thei a ni.

2. Strap chakna atana Viscosity chanvo

2.1 Tensile chakna (Tensile) chakna

Tensile strength hi molecular weight nen a inzat chiah a ni. Polymer chain sei zawk (viscosity sang zawk) hian entanglement point tam zawk a siam a, chu chuan tension hnuaiah a chhe thei lo. PET strap viscosity 0.80 dl/g nei chuan a tlangpuiin break force leh impact resistance lamah 0.60 dl/g resin atanga siam strap a phak lo zawk ang.

2.2 Elongation leh Tension Retention

Viscosity hian strap a inzawm dan pawh a nghawng bawk. High-viscosity PET hian elastic recovery tha zawk a lantir a, chu chu load a settle zel angin hun kal zelah tension a vawng reng tihna a ni. Low-viscosity PET hian a stretch reng thei a, chu chuan transit laiin loose load a thlen thei.

2.3 Environment laka invenna

Material science data atanga a lan dan chuan viscosity sang zawk PET hian viscosity hniam zawk grade aiin UV degradation leh thermal aging a do tha zawk a ni. Hei hian hun rei tak pawn lama dah emaw, tuipuiah emaw a kal laiin strap chu a chakna a vawng reng thei a ni.

3. Viscosity dik lo avanga thil thleng

3.1 Viscosity a hniam lutuk (< 0.60 dl/g) a nih chuan .

• Brittle strap : Tensioning laiin strap hi a chhe thei a, a inthen thei bawk.

• Low break force : Strap chu a dik taka tarlan load-in a phur theih tur load hnuaiah a fail thin.

• Performance inmil lo : Batch hrang hranga inthlak danglamna hian production line a titawp thin.

3.2 Viscosity a sang lutuk (> 0.95 dl/g) a nih chuan .

• Processing chungchang : Viscosity sang tak nei resin hi a harsa hle extrude leh stretch a ni a, hei hian energy consumption sang tak leh equipment wear a thlen thin.

• Stiffness : Strap hi a rigid lutuk thei a, package shape nen a inmil lo thei a, load stability a ti tlem thei.

4. Jushuo Packaging hian Viscosity a control dan

Jushuo Packaging-ah hian viscosity hi chance-ah kan dah lo. Kan PET resin intrinsic viscosity control leh stabilize nan Solid State Polymerization (SSP) technology kan hmang a.

Kan production data atanga a lan dan chuan SSP technology hmang hian 0.60 atanga 0.95 dl/g range chhungah viscosity chiang takin kan siam thei a ni. Hei hian PET strap batch tin hian target tensile strength leh durability a neih theih nan a pui a ni. Laboratory testing khauh tak hmangin viscosity kan verify a, strap siam zawh tawh chuan heavy-duty industrial application atana mamawh performance a pe chhuak tih kan enfiah thin.

5. Supplier Viscosity Control chungchang endik

5.1 Document siam dan tur

PET strap supplier i thlan dawnin raw material specification zawt thin ang che. Supplier rintlak tak chuan resin-a intrinsic viscosity leh finished strap-a mechanical property te documentation a pe ang. He transparency hian viscosity control hi an quality management system-ah a tel tih a tilang chiang hle.

5.2 Sample Testing neih dan tur

Sample dil la, test rawh. Quality best practices ang chuan:

1. Tensile Test : Break force chu specification nen a inmil em tih enfiah rawh.

2. Elongation Test : Load hnuaia strap chu engzat nge a inzawm tih teh rawh.

3. Visual Inspection : Processing tha lo tilang thei tur surface defects awm leh awm loh enfiah thin ang che.
