I-polyester spunbond vs. i-polypropylene spunbond: umboniso wokugqibela wetekhnoloji ekukhethweni kwezinto

Ukusebenza okungundoqo: iyantlukwano ebalulekileyo kwiimpawu zokuzalwa

1. Iimpawu zoomatshini kunye nokuzinza

I-polyester spunbond: Yenziwe kwi-polyester (PET) njengento ekrwada, amandla okuqina angafikelela kwi-1.5-2 amaxesha e-polypropylene, kunye ne-longitudinal kunye ne-transverse yamandla umahluko ongaphantsi kwe-5%, kunye nesantya sokugcinwa kwamandla ngaphezu kwe-90% kwimeko emanzi, efanelekileyo kwiimeko zexesha elide loxinzelelo. Ukumelana nokukhanya kwayo okwesibini kuphela kwi-fiber ye-acrylic, kwaye emva kweeyure ze-1000 zokukhanya kwelanga, amandla ayo asenokugcinwa nge-60-70%. Ubomi bayo benkonzo yangaphandle bunokufikelela ngaphezu kweminyaka emi-5. ​

Polypropylene spunbond: Ubuninzi beiipolypropylene (PP) izintoyi 0.91g/cm ³ kuphela, nto leyo eyenza ukuba ibelelona didi lukhaphukhaphu phakathi kwemicu yekhemikhali eqhelekileyo. Ubunzima beemveliso ezinobunzima obufanayo bungama-30% aphezulu kune-polyester, kwaye i-fluffiness ingcono. Kodwa inozinzo olulambathayo lwe-thermal, ithambile kwi-70-80 ℃ kunye ne-melting deformation ngaphezulu kwe-150 ℃. Ikwanazo nokumelana nokuguga okubuthathaka kwaye ithanda ukuba brittleness xa isetyenziswa ngaphandle ngaphandle konyango lwe-UV. ​

2. Ukunyamezelana kweMichiza kunye nokusiNgqongileyo

I-Polyester spunbond inoluhlu lwexesha elide lokumelana nobushushu obuyi-260 ℃ kunye noluhlu lwexesha elifutshane lobushushu obuyi-300 ℃. Ayinyangeki ngamachiza, ayinyangeki ngeasidi, kwaye ayinyangeki ngealkali, inesantya sokufunxa ukufuma esingaphantsi kwe-0.5%. I-antibacterial, ubungqina benundu, kunye nobungqina bokungunda.

I-Polypropylene spunbond inoluhlu lwexesha elide lokumelana nobushushu obuyi-120 ℃ kunye noluhlu lwexesha elifutshane lwe-150 ℃. Iyakwazi ukumelana neekhemikhali, i-acids, i-alkalis, kunye neninzi ye-solvents yezinto eziphilayo, kunye nesantya sokufunxa ukufuma ≈ 0%. Inokufunxeka kakuhle okungundoqo kunye neepropathi zokulwa ne-antibacterial, ukwahlula ukhukuliseko lwebhaktiriya kunye nokufezekisa iipropati ezingcono zokulwa ne-antibacterial.

3. Ukuziqhelanisa nokusebenza

I-polyester spunbond: Ubuninzi obuphezulu bunokufezekiswa ngokuqiniswa okushushu okuqengqelekayo, kunye nokungena komoya kunokulawulwa phakathi kwe-50-500L/m² · s, ilungele izixhobo zokucoca; I-Polypropylene spunbond: Isigxothi sendalo samanzi (i-engile yoqhagamshelwano> 130°), sinokusetyenziselwa umphezulu wemveliso yococeko emva kokuguqulwa kwe-hydrophilic, kunye nesantya sokufunxa esingundoqo esiyi-0.3cm/s. ​

Iimpawu zenkqubo: ukuhlukana kwezobuchwepheshe ekupheleni kwemveliso

1. Ukuthelekiswa kweeparamitha eziphambili zokujikeleza

Iqondo lobushushu lePolyester spunbond elisontayo yi-285-290 ℃, isantya sokuzoba yi-4000-6000m/min, i-screw aspect ratio kufuneka ibe ≥ 27, ukunyangwa kwempahla ekrwada kufuneka yome (umxholo wokufuma<0.05%);I-Polypropylene spunbond⃃20-20 isantya sokujikeleza, umzobo we-92⃃ malunga nesantya sokusonta malunga ne-92⃄2 2000m/min, ubude bobude be-screw diameter ratio yi-25-27 xa kuthelekiswa nesiqhelo, kunye nonyango lwangaphambili alufuni ukomiswa.
​
2. Izixhobo kunye noLawulo lweeNdleko

I-polyester spunbond: ifuna izixhobo zokomisa ezikhethekileyo, ngokusetyenziswa kwamandla nge-15-20% ephezulu kune-polypropylene, kodwa imveliso egqityiweyo inobunzima obuchanekileyo obuchanekileyo (± 2g/m²); I-Polypropylene spunbond: iyahambelana ne-30% yokongeza izinto ezisetyenzisiweyo, utyalo-mali lwezixhobo lungaphantsi nge-10-15%, kunye nokusebenza kakuhle kwe-high-frequency hot melt processing yi-30% ephezulu kunepolyester. ​

Imeko yesicelo: ingqiqo yokhetho ejolise kwimfuno

1. Ukwahlulwa kweendawo eziphambili zezicelo

Ukhetho olukhethiweyo lokhuseleko lwezonyangopolypropylene ispunbond(isakhiwo seSMS), esinezixhobo ezinamandla zokulwa ne-antibacterial kunye ne-non-toxic, kunye nokusebenza kakuhle kokucoca okungaphezulu kwe-95%.

I-polyester spunbond ikhethwa kuhluzo lwamashishini ngenxa yokumelana nobushushu obuphezulu, ubungakanani obuzinzileyo, kunye nokukwazi ukucocwa ngokuphindaphindiweyo.

Olona khetho lukhethwayo lokhuselo lwezolimo yi-polypropylene spunbond (i-UV ukumelana), kunye nesizathu esingundoqo kukuba i-polypropylene spinning inokukhanya okubonakalayo, ixabiso eliphantsi, kwaye inokuthotywa ngokwendalo kwiminyaka eyi-1-5.

Eyona nto ikhethwayo kwizinto zangaphakathi zemoto yi-polyester spunbond, esona sizathu siphambili kukunganyangeki kwayo ukwaluphala, ukugqunywa kwesandi esilungileyo, kunye nokuxhathisa ixesha elide kumaqondo obushushu ukuya kuthi ga kwi-120 ℃.

Olona khetho lukhethwayo kwiimveliso zococeko yi-polypropylene spunbond, kunye nesizathu esingundoqo sokuba i-polypropylene spunbond core inokufunxeka ngokukhawuleza, iipropathi zokugxotha amanzi, kunye nokuchukumisa okuthambileyo.

2. Uhlalutyo lwemeko eqhelekileyo

Igawuni yotyando yezonyango: yenziwe nge30g/m² ilaphu le-polypropylene SMS ehlanganisiweyo, iphathwa nge-anti-alcohol kunye ne-anti plasma iimpawu, kunye nokungena kokufuma kwe->2000g/m² · 24h;Ibhegi yokucoca ubushushu obuphezulu: Yenziwe nge-200g/m ² ilaphu le-polyester spunbond yaze yagqunywa ngebhanyabhanya nge-bePT02 ngokuqhubekekayo. ℃; Ilaphu elinobungqina bengca: 60g/m² ilaphu le-UV elinganyangekiyo lepolypropylene spunbond, elinamandla anqamlezayo akrazuka angaphezu kwe-80N, kunye nobomi benkonzo ukuya kuthi ga kwiminyaka emi-3. ​

UQoqosho kunye nePhatheni yeMarike

1. Uthelekiso lokwakhiwa kweendleko (uthatha i80g/m ² imveliso njengomzekelo)

Iindleko zempahla ekrwada: Iitshiphusi zePolyester (8500 yuan/ton) vs iitshiphusi zepolypropylene (7200 yuan/ton), kunye neetshiphusi zepolypropylene zibe 15.3% ngaphantsi; Iindleko zokulungisa: Ipolyester (1.2 yuan/m²) vs Polypropylene (0.9 yuan/m²), iPolypropylene ngama-25% ngaphantsi; Iindleko ezipheleleyo: I-Polypropylene spunbond yi-18-22% ngaphantsi kwe-polyester. ​

2. Isabelo semarike kunye neendlela

Kwilaphu le-global spunbond nonwoven, i-polypropylene ibalelwa malunga ne-70% kunye ne-polyester i-akhawunti ye-18%; Kwicandelo lezonyango, ubungakanani bepolypropylene SMS Umthamo wokuvelisa unyukile ukusuka kwi-12% ngo-2020 ukuya kuma-37.6% ngo-2024, kwaye kulindeleke ukuba udlule kwi-48% ngo-2025; Kwintsimi yezoshishino,i-polyester spunbondizuze isantya sokukhula sonyaka se-8.2% kwimarike yokuhluza lobushushu obuphezulu ngenxa yokuphuculwa komsebenzi. ​

Ukhuseleko lokusiNgqongileyo kunye noPhuhliso oluZinzileyo

Ukurisayikilisha: Zombini zizinto ze-thermoplastic. Ukurisayikilishwa kwePolyester kufuna ukunyibilika kobushushu obuphezulu (ukusetyenziswa kwamandla aphezulu), ngelixa i-polypropylene recycling ifuna ubushushu obuphantsi (30% ukonga amandla). Nangona kunjalo, izinga lokugcinwa kwamandla e-polyester esetyenzisiweyo yi-85%, engcono kune-polypropylene ehlaziyiweyo (70%);

Iimpawu zokuthotywa: I-Polypropylene inokufezekisa ukuhlukana kwendalo iminyaka eyi-1-5 ngokongeza i-degradation masterbatch, ngelixa i-polyester idinga iimeko ezithile ze-enzymatic hydrolysis kunye nomjikelezo wokuthotywa kweminyaka engaphezu kwe-20; ​

I-Carbon footprint: Imveliso ye-Polypropylene ikhupha malunga neetoni ze-3.2 ze-CO ₂ ngetoni, ephantsi kune-polyester (i-5.1 iitoni ze-CO ₂). ​

Ultimate Choice Guide

Ukuqala kufuneka kunikwe i-polypropylene spunbond: xa imfuno iphantsi kwexabiso eliphantsi, i-lightweight, i-repellent yamanzi, i-lahlway (njengeemaski, iimveliso zococeko, ukukhuselwa kwexeshana); ​

Okuphambili kufuneka kunikwe i-polyester spunbond: xa imfuno ingamandla aphezulu, ukumelana nobushushu obuphezulu, ukumelana nokuguga, kunye nokusetyenziswa kwexesha elide (njengezinto zokucoca zoshishino, izinto zokwakha zangaphandle, kunye nezinto zangaphakathi zemoto); ​

Iimeko ezikhethekileyo: Khetha i-polypropylene SMS composite yokhuseleko lwezonyango oluphezulu, ifilimu yepolyester yokucoca ubushushu obuphezulu, kunye ne-UV enganyangekiyo yepolypropylene yokugubungela ixesha elide kwezolimo. ​
