Musiyano pakati pe meltblown uye spunbond

Meltblown jira uye jira risiri rakarukwa ndizvo chaizvo zvakafanana. Meltblown fabric zvakare ine zita rinonzi meltblown non-woven fabric, rinova rimwe remachira akawanda asina kurukwa.Spunbond jira risiri rakarukwaimhando yejira rakagadzirwa kubva kupolypropylene seyakagadzirwa, iro rinoitwa polymer kuita mesh kuburikidza nepamusoro-tembiricha kudhirowa, uyezve kusungirirwa mumucheka uchishandisa inopisa kukungurutswa nzira.

Yakasiyana maitiro matekinoroji

Spunbond jira risiri rakarukwa uye rakanyungudutswa rakafefeterwa risiri-yakarukwa jira ese ari maviri emhando yejira risiri rakarukwa, asi maitiro avo ekugadzira akasiyana.

(1) Zvinodiwa zvezvigadzirwa zvakasiyana. Spunbond inoda MFI ye20-40g/min yePP, nepo kunyungudutswa kunoda 400-1200g/min.

(2) Tembiricha yekutenderera yakasiyana. Melt blown spinning i50-80 ℃ yakakwirira kupfuura spunbond spinning.

(3) Kutambanuka kwemafayibha kunosiyana. Spunbond 6000m/min, inonyunguduka inoputika 30km/min.

(4) Nhambwe inotambanuka haisi cylindrical. Spunbond 2-4m, nyunguduka inoputika 10-30cm.

(5) Kutonhora uye kutambanudza mamiriro akasiyana. Spunbond fibers inodhonzwa uchishandisa 16 ℃ mhepo inotonhora ine yakanaka/negative pressure, ukuwo mafiber akanyunguduka achipeperetswa achishandisa pedyo ne200 ℃ mweya unopisa mukamuri huru.

Kushanda kwechigadzirwa kwakasiyana

Simba rekupwanya uye kurebesa kwejira re spunbond rakakwira zvakanyanya kupfuura iro rejira rakanyungudika, uye mutengo wakaderera. Asi ruoko runonzwa uye kufanana kwefiber hazvina kunaka.

Meltblown jira rakapfava uye rakapfava, rine yakakwirira kusefa kunyatsoita, kushoma kuramba, uye kuita kwakanaka kwezvipingamupinyi. Asi ine simba rakaderera uye kushomeka kwekusagadzikana.

Kuenzanisa kwemaitiro maitiro

Humwe hunhu hwekunyungudutswa machira asina kurukwa ndewekuti faibha yakatsetseka idiki, kazhinji isingasviki 10um (micrometers), ine faibha zhinji dzine hunyoro huri pakati pe1-4um.

Masimba akasiyana-siyana pamutsara wese wekutenderera kubva pamuromo we meltblown anofa kune chigadziro chekugamuchira hachikwanisi kuchengetedza chiyero (nekuda kwekushanduka-shanduka kwesimba rekutambanudza kunokonzerwa nepamusoro-tembiricha uye nekumhanya-mhanya kwemhepo, pamwe nekufurira kwekutonhora kwemhepo uye tembiricha), zvichikonzera kusiyana kwakasiyana kwefiber yakanyunguduka.

Kufanana kwe fiber dhayamita mu spunbond nonwoven fabric web iri nani zvakanyanya pane iya yakanyunguduka faibha, nekuti mu spunbond process, mamiriro ekuruka akadzikama-mamiriro, uye kuchinjika kwekutatamuka uye kutonhora mamiriro kudiki.

Kuenzanisa kweCrystallization uye Oriental Degree

Iyo crystallinity uye kutaridzika kwe melt blown fiber idiki pane iyo yespunbond fibers. Naizvozvo, kusimba kwemafiber akanyunguduka kwakashata, uye simba redandemutande rakashata zvakare. Nekuda kwekusasimba kwakashata kwefiber yekunyunguduka akafefeterwa machira asina kurukwa, iko kushandiswa kwemachira akanyunguduka asina kuruka anonyanya kutsamira pahunhu hwemafiinzi awo ekupedzisira.

Kuenzanisa pakati pekunyunguduka kwakaputika fiber uye spunbond fibers

Fiber kureba - spunbond ifaibha refu, yakanyungudika ipfupi faibha

Simba reFiber - spunbond faibha simba> meltblown faibha simba

Fiber fineness - Meltblown fibers yakanaka kudarika spunbond fibers

Kuenzanisa uye pfupiso ye spunbond uye meltblown maitiro

Zvinhu zvakasiyana

1. Simba uye kusimba: Kazhinji, simba uye kusimba kwespunbond machira asina kurukadzakakwirira kudarika dzemachira asina kuruka akanyunguduka. Mucheka weSpunbond usiri wakarukwa une simba riri nani uye unotambanuka, asi unotambanudza nekuremara kana wadhonzwa; Zvisineyi, jira rakanyungudutswa risiri rakarukwa harina kutatamuka uye rinoda kutsemuka kana radhonzwa nesimba.

2. Kufema: Chigadzirwa cheSpunbond chisina kuruka chine kufema kwakanaka uye chinogona kushandiswa kugadzira masiki ekurapa nezvimwe zvigadzirwa. Zvakadaro, jira risiri rakarukwa rakanyungudika harifemeke zvakanaka uye rinonyanya kukodzera zvigadzirwa sembatya dzekudzivirira.

3. Mushonga uye Mushonga: Mucheka weSpunbond usina kuruka une chimiro chakaoma uye chinodhura, asi chimiro chayo uye kufanana kwefiber hazvina kunaka, izvo zvinonyanya kuenderana nezvinodiwa zvezvimwe zvigadzirwa zvemafashoni. Meltblown jira rakapfava uye rakapfava, rine yakakwirira kusefa kunyatsoita, kushoma kuramba, uye kuita kwakanaka kwezvipingamupinyi. Asi ine simba rakaderera uye kushomeka kwekusagadzikana.

4. Kumusoro kwejira re spunbond risiri rakarukwa kazhinji rine madoti mapatani ari pachena; Uye jira risiri rakarukwa rakanyunguduka rine nzvimbo yakati chechetere ine mapeteni mashoma mashoma.

Nzvimbo dzekushandisa dzakasiyana

Nekuda kwezvakasiyana zvivakwa uye hunhu hwemhando mbiri dzemachira asiri akarukwa, minda yavo yekushandisa inosiyanawo.

1. Chirwere uye hutano: Chigadzirwa cheSpunbond chisina kuruka chine kufema kwakanaka uye kubata kwakapfava, kwakakodzera kushandiswa mune zvekurapa uye zvehutano zvigadzirwa semasiki, machira ekuvhiya, etc. Meltblown isina-yakarukwa jira rakakodzera kushandiswa sesefa layer iri pakati pemasiki, zvipfeko zvekudzivirira, uye zvimwe zvigadzirwa.

2. Zvimwe zvigadzirwa: Iyo yakapfava kubata uye kugadzirwa kwemucheka we spunbond isiri-yakarukwa yakakodzera kugadzira zvigadzirwa zvekuzorora, senge sofa inovhara, maketeni, nezvimwe. Meltblown isina-yakarukwa jira ine yakakwirira kusefa inoshanda uye yakakodzera kugadzira zvakasiyana-siyana sefa zvinhu zvigadzirwa.

Mhedziso

Muchidimbu, spunbond nonwoven jira uye meltblown nonwoven jira vane maitiro avo uye akakodzera kuminda yakasiyana. Vatengi vanogona kusarudza zvimwe zvakakodzera zvinhu zvichienderana nechigadzirwa chavo.

Dongguan Liansheng Nonwoven Fabric Co., Ltd., mugadziri wemicheka isina mucheka uye micheka isina kugadzirwa, akakodzera kuvimba kwako!
