Yintoni i-spunbond nonwoven

Ethetha ngayoilaphu le-spunbond elingalukwanga, wonk’ ubani ufanele aqhelane nayo ngenxa yokuba uluhlu olusetyenziswayo lubanzi kakhulu ngoku, yaye phantse isetyenziswa kwiinkalo ezininzi zobomi babantu. Kwaye izinto zayo eziphambili ziyi-polyester kunye ne-polypropylene, ngoko ke le nto inamandla amahle kunye nokumelana nokushisa okuphezulu. Ilaphu elingalukwanga eliphothiweyo luhlobo lwelaphu elingalukwanga elenziwa ngokukhupha kunye nokwelula iipholima ukuze zenze imicu eqhubekayo, ethi emva koko ibekwe kumnatha ize idityaniswe nge-thermal, ikhemikhali, okanye iindlela zomatshini. Inoluhlu olubanzi lwezicelo, kwaye abantu baqhelene neengxowa ezingalukwanga, ukupakishwa okungalukwanga, njalo njalo. Kwaye kulula kakhulu ukuyichonga, ngokuqhelekileyo inokuqina okuhle kwe-bi-directional, kwaye iindawo zayo zokuqengqeleka ziyidayimane.

Umda wosetyenziso

Inqanaba lesicelo leilaphu le-spunbond elingaphothiweyoinokusetyenziswa njengenxalenye yokupakisha iintyatyambo kunye nelaphu elitsha lokupakisha, njl njl. Kwaye ikwasetyenziswa ngokubanzi kumalaphu okuvuna ezolimo. Ukwanabo nobukho bakhe kwiimveliso zonyango nakwimizi-mveliso, ifanitshala yefenitshala, kunye neemveliso zococeko ehotele. Ngoko. Ilaphu elincamathelayo elingalukwanga lokuxelisa linoluhlu olubanzi lwesikali kwaye liveliswa kusetyenziswa umzobo woxinzelelo olulungileyo. Ngenxa yale ndlela, uthungelwano lokuqinisa luqhagamshelwe, kwaye iimveliso eziveliswe ngokusetyenziswa kwefeni yokufunxa zirhabaxa kakhulu, okukhokelela ekoneleni kwefiber enganelanga ngexesha elinye. Oku kungenxa yesi sizathu, akunakwenzeka ukuvelisa iimveliso ezingaphezulu kwe-120 grams ngemitha yesikwere.

Indlela yokwenza ilaphu elingalukwanga

Kwaye inkqubo yokuvelisa inokuguqulwa ngokuguquguqukayo. Ibhokisi ejikelezayo yomgca wemveliso edibeneyo iya kusebenzisa iimpompo ezininzi ezizimeleyo zokulinganisa ukulinganisa ukunyibilika. Kwaye nganye impompo yokulinganisa inikezela ukubonelela ngokubanzi kwinani eliqingqiweyo lamacandelo okujikeleza. Ngenxa yoko, impompo yokulinganisa ingamiswa ngokwemfuno yomyalelo womthengi kwimveliso, emva koko i-baffle yomatshini we-textile inokulungiswa ukuvelisa iimveliso ezigqityiweyo zobubanzi obuhlukeneyo. Ukongeza, xa izikhombisi ezithile zesalathiso seemveliso ezigqityiweyo zingahambelani nemigangatho, amacandelo e-textile ahambelanayo anokutshintshwa ukuze alungelelaniswe.

Yintoni inkqubo esisiseko yokuhamba kwayoilaphu le-spunbond nonwoven?

1. Ukusika kunye nokubhaka

Iitshiphusi zepolymer ezifunyenwe ngegranulation kunye nokuphoswa kwamabhanti othumelo zihlala ziqulethe umyinge othile wokufuma, ekufuneka zomiswe kwaye zisuswe ngaphambi kokusonta.

2. Ukujikeleza

Izixhobo zokusonta kunye nobuchwepheshe obusetyenziswa kwindlela ye-spunbond ngokusisiseko ziyafana nezo zisetyenziswa kwi-chemical fiber spinning. Izixhobo eziphambili kunye nezixhobo zi-screw extruders kunye ne-spinnerets.

3. Zolula

Iintsinga ezisanda kwakhiwa ezinyibilikayo ezisontekileyo (iintsinga eziphambili) zinamandla aphantsi, ubude obuphezulu, ubume obungazinzanga, kwaye azinamsebenzi ofunekayo wokusetyenzwa kwelaphu, ezifuna ukolula.

4. Filamentation

Oku kubizwa ngokuba kukwahlulwa kubhekiselele ekwahlukaneni kweenyanda zefiber ezoluliweyo zibe yimicu enye ukuthintela imicu ekubambeni okanye ukuqhina ngexesha lenkqubo yokwenza iwebhu.

5. Ukubeka umnatha

(1) Ulawulo lokuhamba komoya

(2) Ukuthintela nokulawula oomatshini

(3) Emva kokwelula kunye nokwahlula, i-filament kufuneka ibekwe ngokulinganayo kwi-curtain mesh.

6. Umnatha wokufunxa

Ngokusebenzisa iminatha yokufunxa, ukuqukuqela komoya okuya ezantsi kunokukhutshelwa kude kwaye ukubotshwa kwakhona kwentambo kunokulawulwa. Ke ngoko, kukho ipleyiti yomoya ethe nkqo engama-20 yeesentimitha engqindilili phantsi komnatha wekhethini ukuthintela ukuphuma komoya omva ukuba ungavutheli kumnatha. Ipere yeerola ezingangeni moya zicwangciswe kumda wokufunxa kwicala langaphambili lomnatha wefayibha. I-roller ephezulu inobubanzi obukhulu, ilula, kwaye ixhotyiswe ngemela yokucoca ukukhusela i-roller ukuba ingangeni. Irola esezantsi inobubanzi obuncinci kwaye idla ngokubotshwa ngeerola zerabha ukwenza ikhethini yemesh. Umbhobho oncedisayo wokufunxa ufunxa ngokuthe ngqo kumnatha woxinzelelo lokuhamba komoya, ngaloo ndlela ulawula umnatha wefiber ukuba uncamathele kumnatha womnatha.

7. Ukomelezwa

Ukomelezwa yinkqubo yokugqibela, eyenza ukuba umnatha ube namandla athile, ubude, kunye nezinye iipropati ukuhlangabezana neemfuno zemveliso.

Ukuba ukuphefumla kubi, iqela elijikelezayo elinemingxuma embalwa kwi-spinneret inokutshintshwa, elinokunyusa ukuphefumla kwendawo yelaphu. Ngoku, uxinzelelo lomoya lwendlela enye-cylinder yesikhokelo inokuhlengahlengiswa ukwenza iipropathi ezibonakalayo zobubanzi buphelele bufana. Amandla asecaleni kwelaphu le-spunbond elingalukwanga liphezulu kakhulu, kwaye indlela yokusonta isebenzisa indlela yelaphu ukwenza iwebhu. Iphepha liya kugungxulwa ngokuqhubekayo emva naphambili kwi-frequency ye-750Hz, kwaye i-high-speed stretch fibers iya kungqubana ecaleni kunye ne-mesh.

Amandla eilaphu le-spunbondiphezulu kakhulu kuba umnatha womnatha umkhusane uqhubela phambili ngokwedayagonali kunye nokuhlangana. Ukuqina okuthe nkqo nokuthe tyaba kwamanqaku kunokufikelela ku-1:1. Ngokuqhelekileyo, ukulinganisa kusebenzisa i-Venturi riser, kodwa amandla ayo akaphezulu kakhulu, kwaye amandla e-longitudinal kunye ne-transverse yomelele kakhulu. Iintsinga zamalaphu angalukwanga kwiiwebhusayithi zinokuchasana nobushushu obuphezulu kunye nokumelana nokunxiba, kwaye amandla abo omatshini makhulu kunalawo e-PP fibers.

Yintoni ekufuneka iqwalaselwe ngexesha lokuqengqeleka kwelaphu elingalukwanga le-spunbond?

1. Ngexesha lenkqubo yokujija, lawula ulawulo loxinzelelo lwelaphu elingalukwanga le-spunbond.

2. Xa uxinzelelo luyanda phakathi koluhlu oluthile, ububanzi kunye nobubanzi bei-spunbond nonwoven rollshwabana.

3. Xa ukunyanzeliswa kwenyuka phakathi koluhlu oluthile, kunokunyuswa. Ezona mfuno zoxinzelelo zingentla kufuneka zishwankathelwe kwimveliso yokwenene ukuqinisekisa umgangatho.

4. Ngexesha lenkqubo yokuvelisa, nikela ingqalelo ekujongeni rhoqo ububanzi kunye nobude be-spunbond yelaphu elingaphothiweyo.

5. I-tube yephepha kunye ne-spunbond yelaphu engalukiweyo roll kufuneka ilungelelaniswe.

6. Nika ingqalelo ekuhlolweni komgangatho wembonakalo ye-spunbond engalukiweyo ilaphu, njengokuvuza, ukuphuka, ukukrazula, njl.

7. Pakisha ngokweemfuno zemveliso, nikela ingqalelo ekucocekeni, kwaye uqinisekise ukuba ukupakishwa kuqinile.

8. Isampuli kunye novavanyo lwebhetshi nganye yelaphu le-spunbond elingalukwanga.
