Polyester spunbond vs. polypropylene spunbond: bandhiga farsamada ugu dambeeya ee xulashada walxaha

Waxqabadka asaasiga ah: kala duwanaanshaha lama huraanka ah ee sifooyinka dhalanteed

1. Guryaha makaanikada iyo xasiloonida

Polyester spunbond: Waxaa laga sameeyay polyester (PET) oo ah walxo ceeriin ah, xoogga xajintu waxay gaari kartaa 1.5-2 jeer kan polypropylene, oo leh farqi xoog leh oo dheer iyo dhexdhexaad ah oo ka yar 5%, iyo heerka xajinta xoogga in ka badan 90% xaalad qoyan, oo ku habboon xaaladaha walaaca muddada-dheer. Iska caabbinta iftiinka ayaa ah kan labaad ee kaliya ee loo yaqaan 'acrylic fiber', ka dib 1000 saacadood oo soo-gaadhista iftiinka qoraxda, xooggeeda ayaa weli lagu hayn karaa 60-70%. Nolosheeda adeeg dibadeed waxay gaari kartaa in ka badan 5 sano. ?

Polypropylene spunbond: cufnaantamaadada polypropylene (PP).kaliya waa 0.91g/cm³, taas oo ka dhigaysa qaybta ugu fudud ee fiilooyinka kiimikada caadiga ah. Dhumucda alaabooyinka leh miisaan isku mid ah ayaa 30% ka sarreeya polyester-ka, iyo qallafsanaanta ayaa ka fiican. Laakin waxa ay leedahay xasillooni kulayleed liidata, jilicsanaanta 70-80 ℃ iyo dhalaalid dhalaalaysa oo ka sarreysa 150 ℃. Waxa kale oo ay leedahay iska caabin gabowga oo daciif ah waxayna u nugul tahay jajabnaanta marka bannaanka lagu isticmaalo daawaynta UV. ?

2. Dulqaadka Kiimikada iyo Deegaanka

Polyester spunbond waxay leedahay iska caabbinta heerkulka muddada-dheer oo ah 260 ℃ iyo heerkulka muddada gaaban ee 300 ℃. Waa adkaysi kiimikaad ahaan, aashitada u adkaysata, oo aan alkali adkaysin, oo leh heerka nuugista qoyaanka wax ka yar 0.5%. Waa bakteeriyo-bakteeriya, aboor-caddee, iyo caaryada.

Polypropylene spunbond waxay leedahay iska caabbinta heerkulka muddada-dheer oo ah 120 ℃ iyo heerkulka muddada gaaban ee 150 ℃. Waxay u adkaysataa kiimikooyinka, acids, alkalis, iyo inta badan dareerayaasha organic, oo leh heerka nuugista qoyaanka ≈ 0%. Waxay leedahay nuugista xudunta u wanaagsan iyo sifooyinka bakteeriyada, go'doominta nabaad-guurka bakteeriyada waxayna gaartaa sifooyin bakteeriyada ka wanaagsan.

3. La qabsiga shaqada

Polyester spunbond: Cufnaanta sare waxaa lagu gaari karaa xoojinta duuban kulul, iyo xajinta hawada waxaa lagu xakameyn karaa inta u dhaxaysa 50-500L/m ² · s, oo ku habboon alaabta shaandhaynta; Polypropylene spunbond: Biyo-celinta dabiiciga ah (xagalka xiriirka> 130 °), waxaa loo isticmaali karaa dusha alaabta nadaafadda ka dib beddelidda hydrophilic, oo leh xawaaraha nuugista ee 0.3cm/s. ?

Tilmaamaha habka: kala duwanaanta tignoolajiyada ee dhamaadka wax soo saarka

1. Isbarbardhigga halbeegyada wareegga xudunta u ah

Polyester spunbond heerkulku waa 285-290 ℃, xawaaraha sawirku waa 4000-6000m/min, saamiga muraayada waa in uu ahaado ≥ 27, pretreatment pretreatment alaabta ceeriin waa in ay qalalan (content qoyaan <0.05%); Polypropylene spunbond heerkulka wareega waa 220-29min. Dhererka dhexroorka istaroogga waa 25-27 marka la barbar dhigo kuwa caadiga ah, iyo ka-hortagga alaabta ceeriin uma baahna qallajin
?
2. Qalabka iyo Xakamaynta Qiimaha

Polyester spunbond: waxay u baahan tahay qalab qalajin gaar ah, oo leh isticmaalka tamarta 15-20% ka sarreeya polypropylene, laakiin alaabta la dhammeeyey waxay leedahay saxnaanta miisaanka sare (± 2g/m ²); Polypropylene spunbond: oo ku habboon 30% oo lagu daray walxaha dib loo warshadeeyay, maalgashiga qalabku waa 10-15% hoose, iyo waxtarka dhalaalidda kuleylka kulul ee soo noqnoqda ayaa 30% ka sarreeya polyesterka. ?

Xaaladda codsiga: macquulka xulashada dalabka

1. Qaybinta aagagga codsiga ugu weyn

Doorashada la door bidayo ilaalinta caafimaadka waaspunbond polypropylene(qaab dhismeedka SMS), kaas oo leh sifooyin bakteeriyayaal xoog leh iyo kuwa aan sun ahayn, iyo waxtarka sifaynta ee ka badan 95%.

Polyester spunbond ayaa loo door bidaa sifaynta warshadaha sababta oo ah iska caabin heerkul sare ah, cabbir deggan, iyo awoodda in si isdaba joog ah loo nadiifiyo.

Doorashada la door bidaayo caynsanaanta beeraha waa polypropylene spunbond (UV adkaysi u leh), iyadoo sababta ugu muhiimsan ay tahay in wareegtada polypropylene leedahay viscosity iftiin, qiimo jaban, oo si dabiici ah hoos u dhigi kara 1-5 sano gudahood.

Doorashada gudaha ee baabuurta waa polyester spunbond, iyada oo sababta ugu muhiimsan ay tahay caabbinta gabowga, dahaarka dhawaaqa wanaagsan, iyo caabbinta muddada-dheer ee heerkulka sare ilaa 120 ℃.

Doorashada la doorbido ee alaabta nadaafadda waa polypropylene spunbond, iyada oo sababta ugu muhiimsan ay tahay in xudunta polypropylene spunbond core ay leedahay nuugista degdega ah, sifooyinka biyaha, iyo taabashada jilicsan.

2. Falanqaynta kiisaska caadiga ah

Dharka qalliinka caafimaadka: laga sameeyay 30g/m ² polypropylene SMS ka samaysan dhar, lagu daaweeyay alkohol-ka-hortagga iyo hantida balaasmaha, oo leh qoyaan qoyaan ah>2000g/m ² · 24h ℃; Dharka aan cawska lahayn: 60g/m ² UV adkaysi u leh dharka polypropylene spunbond, oo leh xoog jeexjeexan oo jeexjeexan oo ka weyn 80N, iyo nolosha adeeg ilaa 3 sano ah. ?

Dhaqaalaha iyo Habka Suuqa

1. Isbarbardhigga halabuurka qiimaha (qaadashada 80g/m² badeecad tusaale ahaan)

Qiimaha alaabta ceeriin: Chips Polyester (8500 yuan/ton) vs polypropylene chips (7200 yuan/ton), oo leh chips polypropylene oo 15.3% ka hooseeya; Qiimaha habaynta: Polyester (1.2 yuan/m ²) vs Polypropylene (0.9 yuan/m ²), Polypropylene waa 25% ka hooseeya; Qiimaha dhamaystiran: Polypropylene spunbond waa 18-22% ka hooseeya polyesterka. ?

2. Saamiga suuqa iyo isbeddellada

Marka la eego dunta spunbond ee caalamiga ah, polypropylene waxay xisaabisaa qiyaastii 70% polyester-ka waxay xisaabisaa 18%; Dhanka caafimaadka, saamiga wax-soo-saarka qaab-dhismeedka SMS-ka ee polypropylene wuxuu ka kordhay 12% 2020 ilaa 37.6% 2024, waxaana la filayaa inuu dhaafo 48% marka la gaaro 2025; Dhinaca warshadaha,polyester spunbondwaxa uu gaadhay heerka kobaca sanadlaha ah ee 8.2% suuqa sifaynta heerkulku sareeyo sababtuna ay tahay kor uqaadida waxqabadka ?

Ilaalinta Deegaanka iyo Horumarka Joogtada ah

Dib u warshadaynta: Labaduba waa walxo heerkulbeeg ah. Dib-u-warshadaynta polyester-ka waxay u baahan tahay dhalaalid heerkul sare ah (isticmaalka tamar sare), halka dib-u-warshadaynta polypropylene ay u baahan tahay heerkul hoose (30% badbaadinta tamarta). Si kastaba ha ahaatee, heerka haynta xoogga polyester-ka dib loo warshadeeyay waa 85%, taas oo ka wanaagsan tan polypropylene dib loo warshadeeyay (70%);

Astaamaha hoos u dhaca: Polypropylene waxay gaari kartaa kala duwanaansho dabiici ah 1-5 sano iyadoo lagu darayo masterbatch nabaad-guurka, halka polyester-ka uu u baahan yahay xaalado gaar ah oo enzymatic hydrolysis ah oo leh wareeg nabaad-guur ah oo ka badan 20 sano; ?

Raad Kaarboon: Wax-soo-saarka Polypropylene waxa uu sii daayaa ku dhawaad ​​3.2 tan oo CO ₂ tan, kaas oo ka hooseeya polyester (5.1 tan oo CO ₂ ah). ?

Hagaha Doorashada Ugu Dambeeya

Mudnaanta waa in la siiyaa spunbond polypropylene: marka dalabku yahay qiimo jaban, khafiif ah, ka hortagga biyaha, la tuuri karo (sida waji-xidhka, alaabta nadaafadda, ilaalinta ku meel gaarka ah); ?

Mudnaanta waa in la siiyaa polyester spunbond: marka baahida loo qabo xoog sare, caabbinta heerkulka sare, caabbinta gabowga, iyo isticmaalka muddada dheer (sida qalabka shaandhada warshadaha, qalabka dhismaha dibadda, iyo gudaha baabuurta); ?

Xaalado gaar ah: Dooro isku-dhafka SMS-ka polypropylene ee ilaalinta caafimaadka-dhamaadka sare, filimka polyesterka ee sifaynta heerkulka sare, iyo polypropylene adkaysta UV ee caymiska beeraha muddada-dheer. ?

Waa maxay faa'iidada saamileyda ah ee Dongguan Liansheng Non Woven Technology Co., Ltd.waxa la aasaasay bishii Maajo 2020 Waxay soo saari kartaa midabyo kala duwan oo ah PP spunbond dhar aan tol lahayn oo ballac ah oo ka yar 3.2 mitir laga bilaabo 9 garaam ilaa 300 garaam.
