Ndeapi mabizinesi makuru ekunyungudusa akaputika jira risiri rakarukwa

Polypropylene ndeimwe yeakanyanyambishi zvinhukune micheka isina-yakarukwa, iyo inogona kupa machira asina-akarukwa ane akanakisa emuviri zvinhu.

Chii chinonzi jira risiri rakarukwa

Machira asina kurukwa chizvarwa chitsva chezvakatipoteredza zvine hushamwari izvo zvinosanganisa faibha kana granular mapfupi faibha kuburikidza nemakemikari, mechanical, kana makemikari anoumba nzira, pasina kuronga faibha nenzira yemachira.

Sei kushandisa polypropylene

Polypropylene ndeimwe yeanonyanya kufarirwa machira mukugadzirwa kwemachira asiri akarukwa, kunyanya nekuda kwezvikonzero zvinotevera:

1. Polypropylene ine zvakanaka kupfeka kusagadzikana uye kusimba, izvo zvinogona kuvandudza kusimba uye kusimba kwemachira asina kuruka;

2. Polypropylene iri nyore kugadzirisa uye kuumbwa, zvichiita kuti nzira yekugadzira micheka isina kuruka ive nyore;

3. Polypropylene inonyunguduka pakupisa kwepamusoro uye inogona kupa chisungo chakanaka chemicheka isina kuruka.

Hunhu hwehunyanzvi polypropylene zvinhu zvemachira akanyunguduka

Melt blown special polypropylene material PP is universal thermoplastic polymer, ine hunhu hwesimba rakakwirira, kuvharira kwakanaka, kunyunguduka kwemvura yakaderera, tembiricha yekupisa yekupisa, kuderera kwehudhirowa, kupenya kwakanyanya, uye kunyungudika kwakanaka kunyungudika; Panguva imwecheteyo, ine yakanaka yekunyungudutsa, kuramba mafuta, isina simba acid uye alkali kushorwa, uye isingadhuri uye iri nyore kuwana, saka inoshandiswa zvakanyanya mumunda wefiber.

Maitiro anodiwa kune yakakosha polypropylene zvinhu zvemucheka wakanyunguduka

Nekuda kwehunyanzvi hwekunyunguduka kunoputika tekinoroji, PP mbishi zvinhu zvinoshandiswa seyakakosha zvinhu zvekunyungudusa akafemerwa machira asina kuruka anofanirwa kuita zvinotevera zvinodiwa:

(1) Yakanyanya kunyunguduka index inofanira kuva yakakura kudarika 400g/10min.

(2) Narrow hama molecular weight distribution (MWD).

(3) Yakaderera madota emukati, yakaderera melt index yezvinhu zvakanyunguduka, yakakwira viscosity yekunyunguduka, ichida iyo extruder kuti ipe kudzvanywa kukuru kuti iburitse zvakanaka kubva mugomba remuromo, inoda simba rakawanda rekushandisa uye kuisa iyo meltblown michina kune yakanyanya kudzvanywa; Uye iyo yakanyunguduka haigoni kunyatsotambanudzwa uye kucheneswa mushure mekubudiswa kubva mugomba rekutenderera, zvichiita kuti zvisingakwanisi kuumba ultrafine fibers.

Naizvozvo, chete PP zvigadzirwa zvine yakakwira melt index zvinogona kusangana nezvinodiwa tekinoroji yakanyungudika, kugadzira machira ekupedzisira efiber nonwoven, uye kuderedza kushandiswa kwesimba. Iyo yehukama molecular uremu kugovera kune yakakosha kukanganisa pane zvivakwa, kugadzirisa kuita, uye usability yePP kunyungudika. Pakugadzirwa kwemachira asina kuruka akanyungudutswa, kana huremu hwema molecular huremu hwakawandisa uye paine huwandu hwepamusoro hwehuremu hwema molecular huremu PP, kutsemuka kwePP kunowedzera.

Basa re polypropylene mumicheka isina-yakarukwa

1. Kuvandudza kusimba uye kusimba kwemachira asina kuruka

Nekuda kwekunaka kwayo kupfeka kuramba uye kuoma, kuwedzera polypropylene kunogona kuvandudza kusimba uye kusimba kwemachira asiri akarukwa, zvichiita kuti awedzere kusimba uye kusapfeka.

2. Kuvandudza kusefa kwemachira asina kurukwa

Polypropylene chinhu chine microporous chinogona kusefa zvidimbu zvidiki nekudzora saizi yayo yepore panguva yekugadzirwa kwemachira asiri akarukwa. Naizvozvo, polypropylene inogona kuratidza yakanakisa kusefa kuita mumachira asiri akarukwa.

3. Ita jira risiri rakarukwa riite chimiro chakasimba

Polypropylene inonyunguduka pakudziya kwepamusoro uye inopa kubatana kwakanaka kwemachira asiri akarukwa, ichigadzira chimiro chakasimba pakati pema fiber uye kuita machira asina kurukwa akasimba uye akasimba.

Mhedziso

Muchidimbu, polypropylene, seimwe yemidziyo mikuru yemachira asiri akarukwa, anogona kupa machira asiri akarukwa ane akanakisa emuviri zvimiro uye anoita basa rakakosha mukugadzira machira asina kuruka.
