Ndeupi musiyano uripo pakati pekugovera uye kusanganisa kusanganisa?
Funga nezvekugovera semubvunzo wenzvimbo uye kupararira semubvunzo wehukuru hwemadomasi kana agglomerates. Kufambisa yakakura pigment clump mune imwe chikamu chekunyunguduka kunoshandura nzvimbo yayo. Kutyora iyo clump kuita madiki agglomerates inoshandura kupararira kwayo. Imwe mhedzisiro haigadzirise imwe.
| Mubvunzo | Distributive kusanganisa | Dispersive kusanganisa |
|---|---|---|
| Chii chinofanira kuchinja? | Spatial kufanana kwezvikamu. | Agglomerate kana yakapararira-chikamu saizi. |
| Ko kuyerera kunoita sei? | Kupatsanura, gadzirisa uye batanidza zvinhu. | Isa kushushikana kwakakwana kune deformation kana kuparara. |
| Chii chatinofanira kuongorora? | Kuumbwa kana kuenderana kweruvara pamasampuli akatsanangurwa. | Kusara agglomerates kana phase morphology. |
| Chii chinonzi humbowo husina kukwana? | Saizi yakanaka yechidimbu mune imwe chete saizi. | A yunifomu-inotarisa pellet ruvara. |
Musiyano unotsanangurwa mukatiNC State Extension's screw-functionality guide. Zvizhinji zvezvinhu chaizvo zvinobatsira kune ese ari maviri maitiro. Mubvunzo unobatsira ndewekuti zvinhu zvacho zvinogashira chiyero chinodiwa here, kwete kuti chinhu chiri muchikamu chimwe zvachose.
Pakutenga, nyora zvaunoda sechinhu chinocherechedzwa. Ziva kuti ndezvipi zvinofanirwa kuwedzera yunifomu, izvo zvakaunganidzwa kana zvikamu zvisingatenderwe, uye kuti marabhoritari inozvizivisa sei. Chikumbiro che "kusanganisa zvirinani" chinosiya izvo zvisarudzo zvisina kugadziriswa.
Gwaro iri rine chekuita nekutenderedza twin-screw compounding. Gadzira basa rekushandisa kutanga kana uri kuenzanisa mutsara-chikumbiro kana inopikisa-inotenderera PVC maitiro. Yedusingle-screw versus twin-screw material guideinogadzirisa sarudzo yakakura.
Ongorora chirema usati wachinja sikuruu
Rondedzera chakakanganisika usati wadoma chinotsiva. Isu taizokumbira samples dzakasungirirwa kune imwechete yekushanda nguva seye feeder, kumhanya, tembiricha uye rekodhi rekodhi. Sample isina maitiro ayo anoita kuti zviome kusiyanisa inodzokororwa gadziriso dambudziko kubva mukukanganisika kwechinguvana.

Zvandinotarisa ndisati ndakurudzira kusanganisa kwakasimba
Pandinoongorora dambudziko rekusanganisa mapatya-screw, ndinotanga kupatsanura kusaenzana kuumbwa kubva kune zvidimbu zvisina kuputsika. Madonhwe anooneka mumuenzaniso wepellet haana kukwana kururamisa chikamu chakasimba chekukanya. Ini ndinokumbira resin giredhi, yekuwedzera fomu uye kurodha, ikozvino screw marongerwo, marekodhi ekudyisa, uye sampuli dzakaunganidzwa pasi pemamiriro ekushanda akagadzikana.
Nhanho yangu inotevera ndeyekusimbisa izvo izvo zvinyorwa chaizvo. Ndaizoongorora zvikamu zvezvinhu uye kuenzanisa kukanganisa nemishonga yepakutanga. Agglomerated pigment, resin isina kunyungudutswa uye zvinhu zvakasvibiswa zvinoda mhinduro dzakasiyana. Kuwedzera kusanganisa kusimba usati waziva chirema kunogona kutumira kuferefeta munzira isiriyo. Musiyano pakati pekunyungudika kwakashata uye kusanganisa kwakashata zvakare yambiro yepakati mukatiJim Frankland's single-screw kusanganisa kutungamira.
Kune iyo screw wongororo, ini ndinofunga disc hupamhi, kureba kweblock, stagger angle uye nzira yekufambisa pamwechete. Ini zvakare ndinotarisa zvinhu zvakatenderedza, nzvimbo dzekudyisa uye kuyerwa kubvumidzwa. Kneading block haigone kuongororwa nemazvo kubva pakona yayo chete. Chinzvimbo chayo mukuita uye mamiriro ezvinhu anopinda mairi ane basa.
Ndisati ndakurudzira shanduko, ndaigadzira hwaro hwekubuda, tembiricha yekunyungudika chaiyo, mutoro wekutyaira uye zviyero zvemhando yakakodzera. Ini ndaizoenzanisa imwe yakaruramiswa gadziriso shanduko mushure mekunge maitiro agadzikana, kuchengetedza kuumbwa uye sampling nzira inowirirana. Kana kudya kusina kugadzikana kana kuti zvinhu zviripo zvakapfekwa, ndaizogadzirisa nyaya idzodzo ndisati ndashandisa chikamu chitsva chekusanganisa kubhadhara.
Chiyero changu chekugamuchira ndicho chakatemerwa chigadzirwa. A configuration inobvisa agglomerates anooneka asi ichikuvadza fiber morphology inodiwa kana kudarika miganhu yekushanda haisi kuvandudzwa kunogamuchirwa. Ini ndaizochengeta iyo gadziriso inopa inodiwa yekusanganisa mhando mukati memutsara wekupisa uye mekiniki miganho, pane kuenderera mberi nekuwedzera zvirambidzo nekuda kwekuti muchina unogona kuzvishivirira.
Kuti mapatya-screw extruder anogadzira sei kusanganisa
Flow rearrangement uye kushushikana kwenzvimbo kuita mabasa akasiyana
Kugovera chiito kunobva pakupatsanurwa kwakadzokororwa, kutambanudza uye kurongazve zvinhu. Chiito chekuparadzira chinoda kushushikana kwakakwana kukanganisa chikamu chakapararira kana kukunda kuramba mukati meagglomerate. Shear uye kuwedzera kuyerera kunotsanangura deformation nzira; hazvisi zvakaparadzana zvemhando zvinangwa zvinotsiva kugovera nekupararira.
Charlie Martin'songororo yehunyanzvi ye twin-screw inoenderera kusanganisainotsanangura kupindirana kwezvinhu screw, akazadzwa kugadzirisa matunhu uye kuendesa zvikamu. Kukurukurirana kwayo kwemidziyo kunobatsira pano; Mamiriro ekugadzira mishonga muongororo iyoyo haifanire kuendeswa kune resipi yemapurasitiki eindasitiri.

Mibvunzo inowanzo bvunzwa
Inogona kugovera kusanganisa kuputsa pigment agglomerates?
Distributive mixing inonyanya kugovera zvinhu; haisi pachayo kusimbisa kuti kushushikana kuripo kwakakwana kuputsa agglomerate. Chinhu chaicho chinogona kubatsira kune ese ari maviri ekusanganisa modhi. Ongorora asara agglomerates zvakasiyana kubva kune ruvara kana kuumbwa kufanana usati wafunga kana chimwe chiito chekuparadzira chichidiwa.
Kuwedzera screw kumhanya kunogara kuchivandudza kusanganisa here?
Kwete. Speed is a operating input, ukuwo musanganiswa unogamuchirika uri mugumisiro wechigadzirwa. Enzanisa shanduko yekumhanya nemamiriro ekudyisa, tembiricha yekunyungudika chaiyo, mutoro wekutyaira uye bvunzo dzemhando dzakabvumiranwa.
